Help with nginx & jellyfin (feddit.dk)

So I'm just getting started with selfhosting things, and I have a minor problem which I'm having some trouble solving, as I keep getting a connection refused error when trying to connect:

send() failed (111: Connection refused) while resolving, resolver: 127.0.0.1:53

I run a jellyfin server on a NUC - it works well and is accessible on the private network. I want to have a public URL for this server - and other stuff, eventually.

Here's my setup

I have a subdomain - jellyfin.mydomain.com - pointed to the external IP for my router
I have the router set up to allow remote access, and port forwarding directing all port 80 traffic to my public ip > port 80 on the server
On my server - running ubuntu - I installed nginx
I used the official jellyfin nginx config for access from a subdomain
I edited the server_name variable to match my subdomain

Now, whenever I access the subdomain in a browser I get a 502 Bad Gateway error. The /var/lof/nginx/error.logshows:

2024/05/10 08:26:37 [error] 95335#95335: send() failed (111: Connection refused) while resolving, resolver: 127.0.0.1:53

2024/05/10 08:27:07 [error] 95335#95335: *69 jellyfin could not be resolved (110: Operation timed out), client: 193.29.107.173, server: jellyfin.mysubdomain.com, request: "GET /web/ HTTP/1.1", host: "jellyfin.mysubdomain.com"

I have almost no experience with networking, linux, or nginx :D So I am sure the problem is obvious to someone else....

Can you help?

Hello 👋

You need to edit the below lines

set $jellyfin jellyfin;
resolver 127.0.0.1 valid=30s;

To look like the below

set $jellyfin 127.0.0.1;
#resolver 127.0.0.1 valid=30s;

Edited after reading the full config

Wonderful, thank you :)

I did see that mentioned in the comments in the file, but I was under the impression that I was using DNS via my simply.com domain DNS-record. Thanks!
