I followed the docker installation instructions and added the certificate successfully but I get this status:

400 Bad Request | nginx

host nginx error logs:

I replaced my host IP and domain for privacy

Please see my comments below for more info. I tried putting all text here in the body but it won’t let me post.

EDIT: It is now fixed! What I did is replace the following line in my host nginx:

location / {
         proxy_pass http://localhost:82;
         proxy_set_header Host $host;  <---- replace this
         include proxy_params;
    }

With this:

location / {
         proxy_pass http://127.0.0.1:82;
         proxy_set_header Connection "keep-alive, Upgrade";
         proxy_set_header Upgrade websocket;
         include proxy_params;
    }

      The lemmy service needs access to the external network, too. It’s not in the docs, but there’s a bug on GitHub about it (on mobile, can’t find it).

      I created a third network called lemmybridge and added it to my lemmy service definition.

        Thank you for the tip, I’ve been fighting this damn problem for hours trying to figure out why my instance wasn’t able to make external requests.

        Popped in a third network into the docker compose file and now things seem to be working
