v2rayN Subscription Update Failed: Fix Timeouts, Invalid URLs, and Auto-Update Settings

Troubleshooting Subscription Update Failures

Don’t delete the subscription group or clear nodes that still connect. Updating a subscription means the client sends a request to the subscription server and reads the node list; connecting a node means the core connects to a proxy server. These are separate connections: working nodes don’t guarantee the subscription URL is reachable, and a successful update doesn’t mean every node is online.

In the v2rayN main window, open “Subscription Group” → “Subscription Group Settings.” Select the affected group and check its URL and name. Menu labels may vary slightly by version; use the feature names in the subscription group settings and update menus rather than relying on a specific screenshot location.

1. Record the details: Note the client version, update time, current network, and error message. When taking screenshots, hide the path token and query parameters in the subscription URL.
2. Test one group at a time: Update the affected group first. This keeps logs from multiple groups separate and avoids mistaking another group’s result for the test result.
3. Find the first relevant error: Check the information panel in the main window. For more detail, look for log-related options under “Settings” → “Parameter Settings.” Don’t rely only on the final “Update failed” message.
4. Change one thing at a time: First compare direct and proxied updates, then check the URL and format, and adjust scheduled updates last.

Network Timeouts: Compare Direct and Proxied Updates

A timeout usually occurs during DNS lookup, connection setup, or while waiting for a response. It doesn’t by itself mean the subscription URL is invalid. In the “Subscription Group” menu, try both “Update current subscription (without proxy)” and “Update current subscription (through proxy).” Some versions use similar labels such as “selected subscription”; the key is to know which route the request takes.

Before selecting “through proxy,” make sure the proxy connection works with an existing node and check the local listening port. Find the local port under “Settings” → “Parameter Settings.” For example, if this instance is listening on 127.0.0.1:10808, verify that address rather than copying a port from another device. This is only an example; use the values shown in your interface and logs.

System proxy, proxy settings for subscription updates, and TUN routing are separate controls. Enabling the system proxy doesn’t guarantee that every subscription request uses it. With TUN enabled, system routing may capture requests even when “without proxy” is selected. To compare direct access, you can temporarily disable TUN and restore your original settings afterward. See System Proxy Settings and TUN Mode Explained for details.

Invalid URLs: Diagnose by HTTP Status Code

When copying a subscription URL, keep the full scheme, path, and query parameters. Spaces, line breaks, or localized punctuation added by a chat app—or a missing trailing parameter—can turn it into a different request. Subscription URLs often contain credentials, so don’t submit them to public conversion websites or show the full link in support screenshots.

A status code can narrow down the cause, but it doesn’t replace the server’s explanation. For example, 403 doesn’t always mean your plan has expired; it may indicate a restriction on your network’s exit IP or on the request itself. If the response includes Retry-After, wait for the specified time instead of switching nodes and refreshing repeatedly.

Unsupported Formats: Subscription Content vs. Share Links

A 200 OK response only means the server returned content successfully. If that content is a login page, anti-bot check, or JSON error, it still can’t be imported as nodes. If the update says “no available nodes,” check the response content type before investigating protocol support. Don’t assume every format error is a network problem.

• Subscription URL: Usually an https:// URL that the client periodically accesses to retrieve a set of nodes. The prefix alone doesn’t tell you what format the response uses.
• Base64 subscription: A common format that returns multiple share links encoded together. Base64 is an encoding method, not a connection protocol, and it doesn’t protect the subscription content.
• Single share link: A vmess:// or vless:// link usually represents one node. Import it through a node-import option such as clipboard import, rather than requesting it as an HTTP subscription URL.
• Full configuration file: JSON containing fields such as inbounds and outbounds isn’t necessarily a regular subscription just because of its file extension. Confirm the appropriate import option and core format for your client.

VLESS and VMess are proxy protocols; a subscription is a way to distribute node details. One subscription can include multiple protocols. If your provider offers several client formats, choose the one specifically intended for v2rayN. Protocol fields, transport settings, and security parameters must all be compatible—you can’t “convert” a protocol by changing only the link prefix. See the Protocol Configuration Reference for related details.

Auto-Update Interval: Get a Manual Update Working First

Open “Subscription Group” → “Subscription Group Settings,” select the target group, and find the “Auto-update interval” field. Check that auto-update is enabled for the group. Get one manual update to work before setting a schedule; otherwise, the same error will simply repeat at regular intervals.

Check the unit shown in the interface before entering a value: for a field labeled “minutes,” enter 720 for 12 hours; if your version uses “hours,” enter 12. These are configuration examples, not recommended intervals for every service. Follow the provider’s minimum interval. The behavior of 0 depends on the version—don’t assume it means “refresh now.”

1. Save the group settings, run one manual update, and note when it succeeds and how many nodes the group contains.
2. Leave the client running and keep the device awake while waiting for the next update. This avoids mistaking an update skipped during sleep for an invalid subscription.
3. If your version has a separate proxy option for auto-updates, set it to the route you’ve verified. Don’t assume a manual “through proxy” update permanently changes scheduled updates.
4. If updates fail only after startup, check that the network and proxy core are ready, then try again manually. Don’t rush to shorten the update interval.

Scheduled subscription refresh is a client feature, not a generic field to add to Xray or V2Ray outbound JSON. For configuration locations, see the Subscription Management Guide. Don’t invent an update interval field in the core configuration.

After a Successful Update: Checks and FAQs

Once updates are working again, check the node count and names in the group, then test the connection with one node. If the subscription updates successfully but websites still won’t load, focus on node connectivity, the local proxy, and routing—not repeated subscription refreshes. Use the Routing Rules Guide to check which outbound handles the request.
