I'm having issues with pleroma webui and even some user-uploaded content. API seems to be working, or I imagine I couldn't post this with husky.

I see the following in my nginx logs

2021/03/23 00:02:11 [error] 179593#179593: *84 upstream prematurely closed connection while reading upstream, client: 192.168.3.1, server: social.pcwideopen.com, request: "GET /static/css/app.77b1644622e3bae24b6b.css HTTP/2.0", upstream: "http://192.168.3.84:4000/static/css/app.77b1644622e3bae24b6b.css", host: "social.pcwideopen.com", referrer: "https://social.pcwideopen.com/"

I have tweaked these settings back and forth trying to resolve this.

proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
