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;
    }

    Other info

    • OS: Centos 7

    • DNS: Cloudflare

    • I can curl to localhost:82 in my vps

    I am not familiar to nginx but I think I updated the ports this way:

    docker container proxy internal port 80 expose to port 82 localhost in my host host nginx pickups localhost:82 to expose for my domain.tld:443

    Is this cloudflare dns issue or my setup is wrong?

      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
