Summary of the issue you are facing:

So basically whats happening to me is that im using Tailscale to access Nextcloud.
No matter if im inside my network or outside my network I always get an SSL certificate error, but here’s the kicker:

If I access on my server “localhost:8080” I get the login AIO webpage.
If I access outside my network using tailscale https://myserver.word.worf.ts.net:8080/login
I can also see the login page
Its when I try to access anything other than that page (inside or outside my network) when I get this error:

here’s my apache log:

All seems to be ok,
any idea on where I can start?

Hi @jareza, please post this here: https://github.com/nextcloud/all-in-one/discussions/5439

It’s hard to say from what you shared. Please review your browser console/dev tools and check if there is a redirect to localhost. Nextcloud must be aware of the (public) URL where the user can access the system. This could be lost behind reverse proxy and you might need to setup overwritehost and oder reverse proxy headers to configure right redirect - see 101: reverse proxy for details
