On system dashboard gadgets won't display

[Randal Jew]

I just installed a new instance of Jira Service Desk v3.11 that is based on Jira v7.8.1.

The system dashboard has several display issue for gadgets like the piechart (shown below).  It was working at one point, but not anymore.  Running nginx as a proxy server.  Access server via https://jirasdesk.ms.mycompany.com.

The firewall (i.e. iptables is turned off).  I read the posting on "How to fix gadget titles showing as _MSG_gadget", but it didn't work.  Not sure what to try to fix my problem.

Any help is appreciated.

This error is almost always caused by the server being unable to resolve and talk to itself over your network.

Go to the server command line and test it.  Use curl or wget to fetch your configured <base url> - does it get a chunk of html with a "login" type section?  Or does it time out or error?
