After upgrading our Jira server, it appears that the server is not successfully pulling information from itself.
One identified specific symptom is our dashboard subgroup titles appear as code labels, not their designated titles;
Name's Dashboard
__MSG_gh.gadget.rapid.view.title__
Issue Statistics: idQ Issue Backlog (Products)
__MSG_gh.gadget.rapid.view.title__
The environment for the server is pretty common; Ubuntu 18 OS, installed from .bin, behind an external proxy server.
This has been an issue we've experienced in the past, when our servers were delivered as Dockerfiles, and the solution we applied was to install the haproxy's certificate into the Jira server's java store's cacert file, but the root cause was never identified.
I have done the same this time with no productive results.
