I cannot connect to Joplin.

I’ve set up all my apps to have a custom domain to work locally and externally with a wire guard. All of them work without issue expect Joplin.

Heres the config I’m using

server 
{
server_name joplin.home.MYDOMAIN.com

location / { proxy_pass http://host.docker.internal:30106/ proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; client_max_body_size 2048M; } 

}

Other than that its using the exact same setting as my other apps that are working. On my docker yml for Joplin server I’ve got it pointed to localhost:30106

DNS has been set up the same too

When I try localhost:30106 on my home network it loads fine.

Is there something I’m not doing right? Any feedback appreciated
