WebSocket did not Open: Dashboard failed to load.

[Tsangares]

I had this error when setting up hornet with a dashboard and a domain name with nginx and certbot:

WARN        Dashboard        upgrade websocket error: websocket: the client is not using the websocket protocol: 'websocket' token not found in 'Upgrade' header

Classic I have seen this one before. I went to line 71 of /etc/nginx/conf.d/hornet.conf for:

# hornet dashboard
location / {
    ...
}

Where I added the lines:

    proxy_set_header Connection "upgrade";	
    proxy_set_header Upgrade $http_upgrade;

And that fixed it.

The final section of that file looks like:

# hornet dashboard
location / {
    limit_req zone=hornet_dashboard burst=100;
    proxy_pass http://hornet_dashboard;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_http_version 1.1;
    proxy_pass_request_headers on;
    proxy_set_header Connection "keep-alive";
    proxy_set_header Connection "upgrade";	
    proxy_set_header Upgrade $http_upgrade;
    proxy_store off;
}

I will try to make a PR if I can find it in your ansible.
