FlClash Subscription Import or Update Fails

Most subscription issues come down to the URL itself, network reachability, or format compatibility. Verify the URL first, then check each area.

FlClash guide

This site organizes FlClash download, setup, configuration, and troubleshooting information by platform.

Verify the URL first

The copied URL is complete with no extra spaces or line breaks.
Opening the URL in a browser returns content.
The subscription is within its validity period and quota.

Common symptoms and fixes

Symptom	Possible cause	Fix
Invalid URL	Incomplete URL or spaces	Copy the full URL again
Update timeout	Subscription server unreachable	Retry on a stable network
No nodes	Empty or incompatible content	Ask your provider to confirm the format
Some nodes missing	Format partly parsed	Check format against the current version

Version compatibility

Subscription format support can differ between FlClash versions. If the same URL works in another client but fails here, note the version and search the official Issues for similar reports.
