Hello,
I have a running standalone Flink cluster with 2 task managers and 2 job
manages (one task manager and job manager per machine).
Sometimes, when I restart the cluster I get the following error message:
/
java.util.concurrent.CompletionException:
org.apache.flink.util.FlinkException: No REST endpoint has been started for
the JobManager.

Caused by: org.apache.flink.util.FlinkException: No REST endpoint has been
started for the JobManager./
which prevents the access to the web interface.
AM using version 1.4.2
Any idea on what might be causing this?
Regards,
Pedro.
