Hue: The Cloudera Manager Agent is not able to communicate with this role's web server.

Explorer

After upgrading from CDH 5.7.5 to 5.10.0, Hue's Webserver Status gives error message:

 

"Bad : The Cloudera Manager Agent is not able to communicate with this role's web server."

 

Hue is up-and-running, I just think that the CM agent is unable to see it.

 

I found this in /var/log/cloudera-scm-agent/cloudera-scm-agent.log on the Hue server:

Any help would be most appreciated.
