Getting into self hosting so a lot of this is new to me but I’ve been using vaultwarden for months locally, working perfectly. Now I’m using cloudflare and their tunnel to access my apps, immich & nextcloud worked immediately with no extra config needed but vaultwarden gives a bad gateway error when trying to access externally on my domain.
This issue seems to be with vaultwarden running on my TrueNAS. I’ve update the domain in the TrueNAS config for vaultwarden and in the admin portal of VW. Am I missing something?
