Hi Sven,

Switching from ZdcSocketStream to SocketStream fixes the problem.

Thanks Andrei & Volkert for testing. At least you have a workaround now.

If you want I can give you access to a virtual box installation within the network. The easier solution would be through https://www.teamviewer.com/en/index.aspx

OK, I'll keep that in mind. But first, when I find the time, I have to compare ZdcSocketStream to ZdcSecureSocketStream, since some patches were applied to the latter to solve similar issues. This is all quite tricky stuff.

So adding #beOneShot on some networks that are behind proxies, fails the request.

Well, I was already afraid that (possibly transparent) proxies were involved.

The problem is, it is simply impossible for me to debug this remotely.

One things that you could try is switching the socket stream implementation used by Zn,

ZnNetworkingUtils default socketStreamClass: SocketStream.

to no longer use ZdcSocketStream.
