Description of problem: If I try and change the date range or do anything on fstat.gluster.org, it throws up something like below, "Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application." Request the infra team to check the service at their end, to ensure things are running fine.
The service was failling with failure to resolve the DNS. Restarting the service fixed, and while on it, i also rebooted the VM, in case this was some transient issues due to automated upgrade.
So the reboot also didn't help, as a older configuration did prevent nginx from restarting. This time, that's fixed.
