Enterprise Client Community

Hello,

we encounter instability in client-server communication. The behaviour is non-related to concrete action and occurs randomly.
The error frequency is the higher, the slower the network interface is.
local -> 1%
LAN -> 10%
W-LAN/DSL -> 80%

There is a stack trace on the client-side java console!

Regards,

Andreas

...we never ever saw this message - and there are many usage scenarios over various networks (slow/fast, ...)... - Anyone else who has seen this message yet?

Would it be possible for you to trace the network (e.g. by network sniffer) to see what's going on network level?

Anything else which is "special"? like proxy, firewall, ...?
Do you encounter the same problems when going to the demo zone of CaptainCasa?

Hello.

The problem can be reproduce with these settings:

Systemsteuerung -> Java -> Netzwerkeinstellungen -> Browser-Einstellungen verwenden (use browser settings - IE, no proxy, not on LAN)

When I change settings to "Direktverbindung", there is no problem.
