Additional context I have stop/started/rebooted several times, no effect. I have reinstalled Lightning Terminal and LND, did not resolve the issue.

What does the log for loop show? The error appears to indicated this file does not exist: /mnt/hdd/mynode/loop/mainnet/tls.cert

Can you check to see if that file is there?

Loop is running, status is green, and its log has no entries.

I checked that directory, and there are no files in that directory. Should those cert files be there as part of the setup or cert generating process?

[tehelsper]

Yeah, loop should be creating those certificates. That's very unusual. Can you try a reboot and check the loop log after? Logs are only kept for a certain period of time until they are forgotten.

Ok, rebooted, Loop status is green, running, but here is the log:

Looks like the connection is being refused, which I assume is why the certs aren't being created?

[craxis]

I found the issue. UPnP was disabled on my router, once enabled, these errors went away and Lightning Terminal is now running as expected.
