Hey everyone,

I finally figured out how to get my Lemmy instance up and running. Everything seems to work great except for the fact that I can’t subscribe to any lemmy.ml communities; it just stays stuck at pending. All other communities on other instances subscribe successfully.

Is this an issue on my end or is there an issue with lemmy.ml?

    I’m just using the default one from the instructions, pasted it below. It may also be worth noting that I am using Nginx Proxy Manager on top of all this for ssl. I have set all custom locations (api, feeds, nodeinfo, pictrs) but I have left the advanced section blank.

    worker_processes 1; events { worker_connections 1024; } http { upstream lemmy { # this needs to map to the lemmy (server) docker service hostname server “lemmy:8536”; } upstream lemmy-ui { # this needs to map to the lemmy-ui docker service hostname server “lemmy-ui:1234”; }

    server {
        # this is the port inside docker, not the public one yet
        listen 80;
        # change if needed, this is facing the public web
        server_name localhost;
        server_tokens off;
    
        gzip on;
        gzip_types text/css application/javascript image/svg+xml;
        gzip_vary on;
    
        # Upload limit, relevant for pictrs
        client_max_body_size 20M;
    
        add_header X-Frame-Options SAMEORIGIN;
        add_header X-Content-Type-Options nosniff;
        add_header X-XSS-Protection "1; mode=block";
    
        # frontend general requests
        location / {
            # distinguish between ui requests and backend
            # don't change lemmy-ui or lemmy here, they refer to the upstream definitions on top
            set $proxpass "http://lemmy-ui";
    
            if ($http_accept = "application/activity+json") {
              set $proxpass "http://lemmy";
            }
            if ($http_accept = "application/ld+json; profile=\"https://www.w3.org/ns/activitystreams\"") {
              set $proxpass "http://lemmy";
            }
            if ($request_method = POST) {
              set $proxpass "http://lemmy";
            }
            proxy_pass $proxpass;
    
            rewrite ^(.+)/+$ $1 permanent;
            # Send actual client IP upstream
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    
        # backend
        location ~ ^/(api|pictrs|feeds|nodeinfo|.well-known) {
            proxy_pass "http://lemmy";
            # proxy common stuff
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
    
            # Send actual client IP upstream
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }
    

    }

      So first off, yeah their nginx is not the greatest example. Most of it is fine but check out their ansible example

      So first off, I don’t see HTTPS. Federation will not work without HTTPS, that’s in the troubleshooting guide. You’ll need to get https up and running and have a valid cert. Certbot is very easy to get up and running, I followed this guide

      I don’t know if it matters, but add all of the extra security items from the example guide around HTTPS, I believe Lemmy does depend on some of the extra parameters like ssl_ciphers and protocols to make sure requests are using the correct ones.

      One key nugget of information is that in your http block you should add resolver 127.0.0.11 ipv6=off;, which tells nginx to use 127.0.0.11 as it’s DNS, which is imperative if you are using docker host names. That IP is Docker’s internal DNS, so things like http://lemmy and http://lemmy-ui work.

      server_name should be the external tld. For example, mine is poptalk.scrubbles.tech.

      My entire proxypass for / is as follows, I think yours should work, but this is known working:

           location / {
      
                # The default ports:
                # lemmy_ui_port: 1235
                # lemmy_port: 8536
      
                  set $proxpass "http://lemmy-ui:1234";
                  if ($http_accept ~ "^application/.*$") {
                     set $proxpass "http://lemmy:8536";
                  }
                  if ($request_method = POST) {
                     set $proxpass "http://lemmy:8536";
                  }
                  proxy_pass $proxpass;
                  rewrite ^(.+)/+$ $1 permanent;
                  proxy_http_version 1.1;
      	    proxy_set_header  X-Real-IP $remote_addr;
                  proxy_set_header  Host $host;
                  proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
      	    proxy_set_header  Upgrade $http_upgrade;
                  proxy_set_header  Connection $connection_upgrade;
              }
      

      Make sure you’re also redirecting pictshare (which I believe is deprecated, but if you have issues with pictures:

              location ~ /pictshare/(.*)$ {
                return 301 /pictrs/image/$1;
              }

        Thanks for that info! Unfortunately, trying to get my instance up using that config is proving to be quite difficult with my setup. I found another user with a similar setup to me that posted a guide and even that gives me the same problem with ONLY communities on lemmy.ml

        https://lemmy.dcrich.net/post/1150

        I am using the nginx posted on there, as well as nginx proxy manager on top of it which manages my HTTPS / SSL.

        According to everyone that followed that guide, there are zero issues for them, but for me, nothing works on lemmy.ml which is unfortunate as there are a lot of communities I want to subscribe to on here.
