XMR unresponsive, issue reconfigure

I just built a new 1.8 server using docker yesterday and assigned 2 players with various layouts to it. This morning both players were locked up and the log files were full of this error
"835 2017-04-19 04:30 XMR unresponsive, issue reconfigure.
834 2017-04-19 04:25 Unable to start XMR queue: class java.lang.IllegalArgumentException/java.net.UnknownHostException: Unable to resolve host “cms.example.org”: No address associated with hostname"

This is my first time using docker, I believe I have it configured correctly, this is the output from docker-compose config

I’ve edited your post, just so there are no passwords or your email out there in the open.

Regarding XMR, if it is correctly configured, in docker installation you should only need to adjust the public xmr address in CMS settings - what is it set to please?

Then you can indeed issue rekey command - navigate to Displays page -> edit display -> Advanced tab -> check ‘Reconfigure XMR’ and click save

I figured that out 5 min after posting this. That resolved the issue.
Thanks

It’s amazing how helpful reading the documentation can be.
