Has anyone of you an idea what ist happening here, what could be the problem?
Before the Client Update all was working fine.
* Connection-Server is Version 7.12
* Webinterface is working fine.
If you need more information please let me know 
Best regards

Hi @all,
we have found the issue.
It was a LoadBalancer / Proxy-Problem of the companys IT-Security.
The loadbalancer was not redirecting the TCP packages through the same proxy.
So the Connection-Server has thrown away those packages becaus of a wrong source.
The security guys fixed the loadbalancer and now it is running smooth as before
Thx for your time and ideas.
Best regards

HI agong,
$HOST is an alias for the Name of the connection Server 
I have cleand the hostnames cause our customer / company don´t want to post there Hostnames in the internet.
But we have found the problem ... I will write an reply on the first Thread.
Best regards
