For v2rayN users who have added a subscription but see update timeouts, empty results, or scheduled refreshes that do not run. Start with one manual update to distinguish link, network, and content issues, then set a refresh interval for the subscription group. Avoid repeated retries or deleting every node as a substitute for troubleshooting.
How subscription updates work: a successful download does not guarantee a successful import
A subscription URL is usually an HTTPS link with an access token. v2rayN requests the URL, retrieves the text, then converts supported node descriptions into client configuration. A subscription is not itself a proxy protocol: it can contain nodes using different protocols, such as VMess and VLESS. Even if the subscription URL is reachable, that does not mean every node can connect.
Troubleshooting means distinguishing three outcomes: no response, an error response, or content that contains no parseable nodes. For the first two, check the URL and network; for the third, check the format. Node connection logs on the main screen are separate from subscription download messages, so a single core connection error does not prove the subscription server is at fault.
- Keep a useful record: Update only the affected group and note the time, request method, status code, and full error message.
- Keep working nodes: Record which nodes currently work. Do not clear every subscription group while troubleshooting.
- Protect the URL: Hide tokens, user identifiers, and query parameters when sharing logs. A complete subscription URL may grant direct access to your configuration.
Expired or invalid links: distinguish authentication errors from rate limits
A reset subscription token, expired plan, or disabled account can stop the old URL from returning nodes. Missing a trailing parameter when copying the URL or using a web page URL instead of the subscription URL can cause similar symptoms. Copy the v2rayN subscription URL again from your provider's account page, then compare it with the URL saved in the group. Do not keep pasting the same old URL from chat history.
These are the usual meanings of HTTP status codes, not definitive proof of an account's status. A server may use 403 for an access policy restriction, or return an error message with status 200. Check both the status code and response body, along with any account notifications.
Error: 401 Unauthorized
Cause: The request did not pass server authentication, often because the token is outdated or the URL was copied incompletely. Fix: Get the current subscription URL from your account page, replace the URL for the affected group, and try one manual update.
Error: 403 Forbidden
Cause: The server rejected the request, possibly because of account permissions, the outgoing IP address, or an access policy. Fix: Check your account status and your provider's announcements. If everything else looks normal, compare requests made directly and through a proxy.
Error: 429 Too Many Requests
Cause: Requests from the same account or outgoing IP exceeded the server's rate limit. Fix: Stop clicking refresh repeatedly. If the response includes Retry-After, wait for the specified time, then increase the auto-update interval.
Network issues: test direct and proxied requests separately
v2rayN's subscription menu typically offers update options both with and without a proxy. The labels may vary by version, such as “Update current subscription” or “Update all subscriptions.” For troubleshooting, select the current group to avoid triggering a large number of requests at once. This setting chooses the route used to download the subscription; it does not permanently assign an outbound route to every imported node.
| Result | Most likely cause | Next step |
|---|---|---|
| Direct works; proxy fails | The current proxy exit or local proxy is unavailable | Update without a proxy first, then test the node connection separately |
| Direct fails; proxy works | There is a problem with the network path from your local network to the subscription site | Keep your working nodes and update through a proxy |
| Both methods time out | The URL, DNS resolution, server, or both network paths may be failing | Check the domain, system time, and service notices, then compare using another network |
| Both methods return the same authentication error | An account or URL issue is more likely | Get a new URL instead of repeatedly switching proxy modes |
If DNS resolution fails, check the subscription hostname for typos, then check your system DNS and current network. For an HTTPS certificate error, check your device's date, time zone, and trusted system certificates first; do not bypass the error by disabling certificate verification. A connection timeout only means the request did not complete in time. It does not, by itself, prove a DNS problem.
Proxy loop: the node needed for the update is already down
A common dependency loop occurs when the subscription site requires a proxy, but the current proxy node is down, and you need an updated subscription to get a working node. Repeatedly choosing “Update through proxy” still sends the request through the same failed exit. This is a dependency loop during the update process, not necessarily a routing loop at the packet level.
-
Check the current node
On the main screen, check which server is selected and confirm that it can establish a real connection. A latency reading without a successful connection is not enough to prove that a subscription request will work.
-
Try a direct update
Under “Subscription groups,” choose the option to update the current group without a proxy. If it works, test the new entries before switching the current server.
-
Restore a working route
If a direct connection is unavailable, switch to a previously saved working node or a network that can access the subscription site, then update through a proxy.
-
Check the local listener
Open “Settings” → “Parameter settings” and check the local proxy listener configuration and status. If you configured a proxy port manually in your browser, it must match the current settings. Do not copy the port from another device.
Bottom line: restore one working request route first
Change the subscription URL, proxy node, and network route one at a time. If no working route is available, shortening the auto-update interval will only generate more failed requests. Enable scheduled refresh only after a manual update works again.
Invalid content: a 200 response can still contain no nodes
A 200 OK response from the subscription server only means the HTTP request succeeded. The response body may be a login page, an access verification page, an expired-plan notice, or actual subscription text. v2rayN needs a supported node or subscription format to parse—not just any downloadable file.
- HTML response: If the content starts with
<!DOCTYPE html>or<html, first check whether you received a web page URL, login page, or access verification page. - Empty response: Check whether your account still has available nodes, whether the subscription is disabled, and whether the service provider has announced maintenance.
- Format mismatch: Choose a subscription URL explicitly labeled by the provider as compatible with v2rayN. Do not import a configuration made for another client as a generic node subscription.
- Some entries fail: Check whether your current client and core support the protocols and transport parameters in question. VLESS entries with parameters such as REALITY also require a compatible core.
Base64 is a text encoding, not encryption, and it does not guarantee that the encoded content is valid. Decoding it manually may help identify its structure, but it cannot fix an expired token or unsupported parameters. Do not submit a complete subscription to an unfamiliar online converter. If you need to contact your provider, share the error message and a redacted description of the content type instead.
v2rayN auto-update intervals: set them per subscription group
Auto-refresh is usually configured per subscription group, rather than using one fixed interval for every group. The steps below refer to an interface with an “Auto-update interval (minutes)” field. Punctuation and button locations may vary between desktop and other interface versions; follow the unit shown beside the field. Run one manual update before setting a schedule to distinguish scheduling issues from download issues.
-
Open the group settings
On the main screen, go to “Subscription groups” → “Subscription group settings,” select the group you want to change, and open it for editing. Check the remarks and subscription URL to avoid changing a different group with a similar name.
-
Set the refresh interval
Find “Auto-update interval (minutes)” and enter a positive whole number. For example,
720means 12 hours and1440means 24 hours. These are examples, not client defaults. Follow any minimum interval required by your subscription provider. -
Save and verify
Click “OK” or the save button, then reopen the group to confirm the value was saved. Manually update the group once to make sure the URL and current request route both work.
-
Check the next update
Keep the client running and check the update message or log timestamp after one full interval. If your version has an option for the proxy used during auto-updates, set it to the route you have verified works. Do not assume scheduled updates always use the method from your most recent manual update.
In many implementations, an interval of 0 disables scheduled updates; check the field description for your current version before changing it. The client cannot refresh while the computer is shut down or asleep, or while the client is closed. Whether it catches up immediately at startup depends on the version, so do not treat it as a system-level scheduled service.
| Use case | Example interval | Why this setting |
|---|---|---|
| Nodes rarely change | 1440 minutes (24 hours) | Reduce repeated requests and refresh manually when there is a temporary change |
| Updates need to stay reasonably current | 720 minutes (12 hours) | Increase the refresh rate within the frequency allowed by the provider |
| Troubleshooting an update issue | Temporarily disable scheduled refresh | Run one manual test at a time to avoid cluttered logs and rate limits |
If updates still do not run automatically after saving, first check that you edited the right group, the interval is a positive number, the client stays running, and the logs show whether an update actually ran but failed to download. Do not leave the test interval set to one minute. If multiple devices use the same subscription, the server may count their requests together.
After updates resume: check nodes, routes, and refresh intervals
A success message is only the first sign of recovery. Subscription updates sync configuration, but node availability must be tested separately. Routing determines where subsequent traffic goes and is not automatically correct just because the subscription refreshed successfully. Run a minimal check after recovery, then undo any temporary troubleshooting changes.
- Check the group: Confirm the expected entries appear in the target group and that you have not mistaken nodes from another group for the update results.
- Check the connection: Select a new node and run a real connection test, then use a browser to visit the site you actually need.
- Check the proxy: Check the system proxy or the traffic redirection method you use to make sure apps are actually routed through the proxy when the node is working.
- Check the interval: Restore the planned interval after testing and keep at least one working connection available for future updates.
If you need to keep troubleshooting, see the network and proxy checks in the site's Troubleshooting guide. When contacting your subscription provider, include the time of the issue, the HTTP status or error message, and the results of direct and proxied requests. Do not include the full subscription token.
