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?
Yes, similar to the video guide, I set up a wildcard CNAME record to point to ..net.
I see. I dont know if that works, as I haven't done that, but what worked for me was pointing to the tailnet IP, not the tailnet domain, then disabling expiry for my server on the tailscale dashboard so my IP would stay the same.
