I apologize for the lack of logs but we can only reproduce this in a closed
off network. We are experiencing a similar black screen on the client side
similar to what was described in GUAC-1096
<https://glyptodon.org/jira/browse/GUAC-1096> except we are running Tomcat
7.0.76 behind an Nginx reverse proxy.
I suspect its due to proxy issues on our closed off corp network dropping
connections but could a similar condition arise with WebSockets for an end
of stream as you patched for the HTTP Servlet? We don't see this error when
deploying Guacamole on our normal development environment.
Our reverse proxy config is below:
location /guacamole {
proxy_pass http://server:8080/guacamole;
proxy_buffering off;
proxy_connect_timeout 5s;
proxy_http_version 1.1;
proxy_redirect off;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
}
