-------------------------------------

             Summary: Consider improving the WebUI failed to connect dialog.
                 Key: MESOS-7503
                 URL: https://issues.apache.org/jira/browse/MESOS-7503
             Project: Mesos
          Issue Type: Improvement
    Affects Versions: 1.2.0
            Reporter: Anand Mazumdar


Usually, when your Mesos Master is behind a reverse proxy/LB; the keepalive 
timeout value would be set to a small value e.g., 60 seconds for nginx. This 
results in the persistent connection between the browser and the Mesos master 
breaking resulting in the connection lost dialog. This is very inconvenient 
when debugging using the Web UI.

We should consider making the error dialog less intrusive e.g., update an 
element to signify that a reconnection is in progress similar to what other 
online services like gmail etc. do.

I am attaching a screenshot of the error message.
