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.
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.
