Original GitHub issue: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/931

Currently I have Pydio Cells running behind Nginx Proxy Manager(NPM). The web UI and mobile app work as expected. The issue is with the sync client which need https2 support and to pass grpc port.

This is where I seem to fail. I have tried adding in the advanced tab of my configuration for my host:

server {
listen 33060 ssl http2;
listen [::]:33060 ssl http2;
keepalive_timeout 600s;
# Let's Encrypt SSL
include conf.d/include/letsencrypt-acme-challenge.conf;
include conf.d/include/ssl-ciphers.conf;
ssl_certificate /etc/letsencrypt/live/npm-2/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/npm-2/privkey.pem;
location / {
grpc_pass grpcs://192.168.1.208:33060;
}
error_log /var/log/nginx/proxy-grpc-error.log;
access_log /var/log/nginx/proxy-grpc-access.log;
}

But every time I add this or something similar it either does not work or causes NPM to crash. Using this as a guide for the above code. So what am I missing? Thanks.
