We have a strange behavior seen in our tcpdumps.
The client sends a "Client Hello" and can also be seen on the gateway in the tcpdump but there is no activity on the gateway side.
All other "Client Hello" around this "problem case" are looking ok and they get answered by the gateway with a "Server Hello".
The gateway is also not overloaded.
Release : 10.1
This will be resolved in CR4 for gateway 10.1 , if needed there is hotfix available which can be requested from support
