My nginx.conf for lemmy-nginx is below, sorry if it’s a bit messy. I prefer to comment than remove working config. You’ll have to change

#Beginning of kbin fix
# We construct a string consistent of the "request method" and "http accept header"
# and then apply soem ~simply regexp matches to that combination to decide on the
# HTTP upstream we should proxy the request to.
#
# Example strings:
#
# "GET:application/activity+json"
# "GET:text/html"
# "POST:application/activity+json"
#
# You can see some basic match tests in this regex101 matching this configuration
# https://regex101.com/r/vwMJNc/1
#
# Learn more about nginx maps here http://nginx.org/en/docs/http/ngx_http_map_module.html
map "$request_method:$http_accept" $proxpass {
# If no explicit matches exists below, send traffic to lemmy-ui
default "http://lemmy-ui";
# GET/HEAD requests that accepts ActivityPub or Linked Data JSON should go to lemmy.
#
# These requests are used by Mastodon and other fediverse instances to look up profile information,
# discover site information and so on.
"~^(?:GET|HEAD):.*?application\/(?:activity|ld)\+json" "http://lemmy";
# All non-GET/HEAD requests should go to lemmy
#
# Rather than calling out POST, PUT, DELETE, PATCH, CONNECT and all the verbs manually
# we simply negate the GET|HEAD pattern from above and accept all possibly $http_accept values
"~^(?!(GET|HEAD)).*:" "http://lemmy";

This is the nginx.conf file for my external proxy:
server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name ; include /config/nginx/ssl.conf; location / { include /config/nginx/proxy.conf; include /config/nginx/resolver.conf; # set $upstream_app lemmy; set $upstream_app proxy; set $upstream_port 8536; set $upstream_proto http; proxy_pass $upstream_proto://$upstream_app:$upstream_port; # proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header X-Real-IP $remote_addr; # proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 50M; } } access_log /var/log/nginx/access.log combined; You’ll need to change to the appropriate value. I’m forwarding requests to the proxy container referenced by the compose file
