    However I don’t seem to be able to subscribe to kbin magazines. I can see lemmy sending out the follow message to the kbin servers’ inbox, no error messages, but no activity from the kbin server follows up and it stays at ‘subscription pending’.

    Same here. I haven’t been able to fully subscribe to anything on Kbin. Running my own lemmy instance and I get the magazine added as a community and get the magazine description but subscribing never returns anything. I re-try every once in a while but noting so far. I assume it will be fixed sometime in the future. I may just set up a kbin instance as well but I don’t want to manage both.

    Hopefully this will help someone. This seems to work for me. Subscribed communities update, I am able to post. I’m the only user right now on my server. NPM took me a bit of messing around with the config but I think I have everything working, some of this may be redundant / non functional but I don’t have the will to go line by line to see what more I can take out. Here is how I have it configured. Note that some things go to the Lemmy UI port and some to the Lemmy port. These should be defined in your docker-compose if you’re using that. (Mine is below)

    On the first tab in NPM, “Details” I have the following:

    Scheme: http
Hostname: <docker ip>
Port: <lemmy-ui port>
Block Common Exploits and Websockets Support are enabled.

    On the Custom Locations page, I added 4 locations, you have to do one for each directory even though the ip/ports are the same.

    Location: /api
Scheme: http
Hostname: <docker ip>
Port: <lemmy port>

    Repeat the above for “/feeds”, “/pictrs”, and “/nodeinfo”. The example file they give also says to have “.well_known” in there but as far as I know that’s just for Let’s Encrypt which NPM should be handling for us.

    On the SSL tab, I have a Let’s Encrypt certificate set up. Force SSL, HTTP/2 Support, and HSTS Enabled.

    On the Advanced tab, I have the following:

     location / {

   set $proxpass "http://<docker ip>:<lemmy-ui port>";
   if ($http_accept = "application/activity+json") {

     set $proxpass "http://<docker ip>:<lemmy-ui port>";`
   }
   if ($http_accept = "application/ld+json; profile=\"https://www.w3.org/ns/activitystreams\"") {
     set $proxpass "http://<docker ip>:<lemmy-ui port>";
   }
   if ($request_method = POST) {
     set $proxpass "http://<docker ip>:<lemmy-ui port>";
   }
   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;
 }

    I probably should add in my docker compose file as well… I’m far from a docker expert. This is reasonably close to their examples and others I found. I removed nginx from in here since we already have a proxy. I disabled all the debug logging because it was using disk space. I also removed all the networking lines because I’m not smart enough to figure it all out right now. If you use this, look out for the < > sections, you need to set your own domain/hostname, and postgres user/password.

    There’s another post over here https://fernchat.esotericmonkey.com/post/277 with a similar setup, less stuff in the Advanced tab. If I’m bad at explaining maybe another guide will help.
