Bokeh with NGINX reverse proxy gives a Blank White Screen

Hi,

So there are things about your Nginx config I simply don’t know enough about to really adapt. So I went back to the guidance in the users docs, and found a configuration that is working. I hope that it will prove useful enough as a comparison to get you going and adapt to your setup. For reference, I used Nginx 1.13.5 on Win 10 with Bokeh 0.12.9.

After the two steps below, I navigated to http://192.168.155.129/bokehwhatif in a browser outside the VM and could see and interact with the app as expected.

1. Start bokeh server with this command:

    bokeh serve bokehwhatif.py --allow-websocket-origin 192.168.155.129 --port 5100
   

2. Start Nginx wit this config:

#user nobody;

worker_processes 4;

events {

worker_connections  1024;

}

http {

sendfile on;

tcp_nopush on;

tcp_nodelay on;

keepalive_timeout 65;

types_hash_max_size 2048;

default_type application/octet-stream;

gzip on;

    proxy_set_header Connection "upgrade";

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}
