Zato installation

Hi all,
I try to create a Zato plaforme with all modules separated. All are OK except the zato server.

One server for: Cluster, Webadmin and Scheduler
One server for: load balancing
One server for : ODB Mysql and Redis
Twos servers for : Zato server

I have this error when i try to start my servers:

2020-04-11 23:50:33,167 - ERROR - 124663:DummyThread-7 - zato:57 - Could not handle broker msg:Bunch(action=u'101802', channel=u'startup-service', cid=u'658ef2b5eadf785716779803', msg_type=u'0001', payload=u'', service=u'pub.zato.channel.web-socket.cleanup-wsx'), e:`Traceback (most recent call last):

Hello Patrick,
Is your Zato installation updated?
Please, can you post the output of the command “zato --version”?
Thank you
