Hi selfhosting community :)
I am hosting some services on a NixOS box (Immich, Nextcloud and some others). So far I had no problem reaching my services, just via tailscale when I am not at home.
But now I wanted to branch out and get a little fancy with https setup and a domain, so I can share my services with friends. I followed this guide and got a domain at cloudflare. However I ran into some problems.
The relevant setup:

Nextcloud:
services.nextcloud = {
enable = true;
hostName = "nextcloud.<mydomain>.com";
https = true;
};
Nginx:
services.nginx = {
enable = true;
virtualHosts = {
"nextcloud.<mydomain>.com" = {
forceSSL = true;
useACMEHost = "<mydomain>.com";
};
"immich.<mydomain>.com" = {
forceSSL = true;
useACMEHost = "<mydomain>.com";
locations."/".proxyPass = "http://127.0.0.1:2283/";
};
"immich.<machine>.<tailnet>.net" = {
locations."/".proxyPass = "http://127.0.0.1:2283/";
};
};
};
ACME
security.acme = {
acceptTerms = true;
defaults.email = "my@mail.com";
certs."<mydomain>.com" = {
domain = "*.<mydomain>.com";
group = "nginx";
dnsProvider = "cloudflare";
dnsPropagationCheck = true;
credentialsFile = config.sops.secrets.cloudflare.path;
};
};
My situation now is the following:
- I can reach eg. Immich by going to http://..net:2283 (https is not working here).
- I can not reach Immich by the domains I have setup in my Nginx configuration. So "immich...net" & "immich..com" give a "Server not found" error. I tried both 127.0.0.1 and the tailscale IP of the server in the proxyPass section.
Does one of you network wizards know where the problem lies? Or how would I go about troubleshooting the issue?
This approach largely works, with the caveat that it then requires you to always be on the tailnet. If someone wants to connect locally AND via tailnet using the same URL, they'll need to push/advertise routes (or do some other hacky thing)
If you run adguard home it's pretty easy. Just add a DNS rewrite to your local IP.

Yes, in order to access my domain on my local network, I have my pihole instance point the domain to my server's local IP.
I don't have a problem to always be on the tailnet with my client devices, but it does not work even for this case.
