Yes, I think websockets would also need to be supported by your Nginx, although
I'm not sure how to exactly configure this setup with two servers.
In our Nginx setup, WS connections are configured by
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_http_version 1.1;
proxy_pass http://$upstream;
(only) for the route /streampipes/ws, see [1]
So it might be worth a try to add this to your Nginx config as a route, e.g.
location /streampipes/ws {
set $upstream ROUTE_TO_STREAMPIPES_NGINX;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_http_version 1.1;
proxy_pass http://$upstream;
}
I'm quite sure that this is not the 100% correct setup for your case, but hope
this still helps a bit!
