That is an exempt from the client log, can you check the JobManager log?
It could have crashed, and if so the cause is hopefully in there.
Did this issue suddenly occur; as in have you run a job successfully on
the system before? (to exclude network configuration issues)

I do not understand what could be the root cause of this… the IPs look
ok and there is not firewall to block things…

Hello,
the first step is always to check the logs under /log. The JobManager
log in particular may contain clues as why no connection could be
established.

Hi,
I am trying to submit a jar via the console (flink run my.jar).
The result is that I get an error saying that the communication
with the jobmanager failed: Lost connection to the jobmanager.
Can you give me some hints/ recommendations about approaching this
issue.
Thanks
