Describe the Bug

I have to constantly restart pangolin-cli for it to keep accessing my site.

I have pangolin running on one VPS. I have dokploy running on another. I can run pangolin up and access the dokploy web interface via: http://dokploy-admin.pangolin:3000/ and I can run through all the settings, etc. Once I leave it for ~30 seconds I cannot connect again until I run pangolin down && pangolin up

These are the logs:

Hi @danieldonaldson
I have the exact same problem on fedora with the pangolin cli. I constantly have to reconnect for accessing my private resources. Do you still have this problem or did you find a solution/workaround?

@LaurenceJJones commented on GitHub (Apr 1, 2026):

When you run the cli can you add --attach to the pangolin up command so we can see the logs that the client is generating.

As by default the client should be pinging the tunnel path every 5 seconds so there could be something that is denying this path. Also 30 seconds doesnt seem accurate as the code looks for at least 2 minutes of staleness but this could be confusing when the olm client is reusing the previous credentials.
