I have migrated yet again, no errors in the log.
However according to documentation, firezone still uses IP:443 as web ui port, therefore my nginx reverse proxy would proxy it, like before.
Neither does https://IP work, ERR_CONNECTION_REFUSED.
My .env has everything filled including EXTERNAL_URL. (Tried changing that to IP as well.)
Nginx does get request from internet but doesn't get reply from firezone. (Either external_url config)
