Dashboard gadgets name display like " __MSG_gadget.*.title__"

[Marat]

I found a description of the problem in the documentation. 
https://confluence.atlassian.com/jirakb/how-to-fix-gadget-titles-showing-as-__msg_gadget-813697086.html
But none of this is my case.
In log :

[Nic Brough -Adaptavist- · Accepted solution]

The (rather ill-defined, but always) root cause of this is "Jira can not call its own REST API on this machine".

Your error message is clear.  When the Jira user on the server (the user running Jira) tries to reach "jiraxxx.xxxx.com", the operating system is unable to resolve that to a server.

You need to fix your DNS, such that jiraxxx.xxxx.com resolves correctly.
