Umbrel GUI stuck on loading due to LND not working

[anrath]

See debug logs here.

General Info

The Umbrel GUI is stuck on loading with the web console displaying an error with GET http://10.10.10.237/api/v1/lnd/info/status 500 (Internal Server Error). A previous error shows Failed to load resource: the server responded with a status of 500 (Internal Server Error) api/v1/lnd/info/status:1 ("ENOENT: no such file or directory, open '/lnd/tls.cert'")

A look at the debug logs confirms that something is wrong with lnd. See this line from the debug logs: lnd | unable to open databases: unable to obtain database backends: invalid argument.

Debugging steps taken

1. Unbuntu 20.04 is fully patched and current
2. Tried reinstalling/updating Umbrel and dependencies
3. Pretty much tried all standard debugging steps except nuking the whole filesystem and starting over.

Notes

• Bitcoin mainnet is fully downloaded and seems to be running smoothly
• Working on a VM
• My intuition/past experience suggests this may be a Docker problem

I have the same issue, followed the README steps end-to-end but also see that error while the GUI polls the backend. Is there another ENV variable that needs to be set or do we need to generate the /lnd/tls.cert file?

Same issue with Raspberry Node 4GB. Below is my screenshot on LND docker log. Currently only solution is to ssh & reboot whole OS.

Got the same error on a fresh install. I'm running Ubuntu 21.04 with Docker 19.03.13 installed from Snap (during OS install). Afterwards, I added my user to the docker group to be able to execute commands without root and setup Umbrel.

The Umbrel GUI /api/v1/lnd/info/status API call breaks with "ENOENT: no such file or directory, open '/lnd/tls.cert'". Checking container logs with docker-compose logs lnd returns:

Maybe you port 8080 is occupied by another process? We had this on our server. So we change the port on this line: https://github.com/getumbrel/umbrel/blob/b2c034c95ed7cbcdc378955cdd0eee63a74eca3d/scripts/configure#L121

Ah damn, since last update the change will be overriden. Still 8080. Ok so now we need to change the port of the other app...whew.
