The UWL iview falls into timeout. Internal port number used while outside of network

Hallo,

When accessing portal from outside the network the UWL iview is not

working correctly. On the other hand when starting the same iview from

inside the network there is no issue.

This is the part of the trace when accessing from outside the network.

In the logs it can be seen that the uwl session is trying to be started

with an internal port number (50001) while being outside the network.

The 50001 port should be 443 when accessing the portal from outside.

We have tried to fix this with proxy mapping. Proxy mapping fixes the problem

when accessing from the outside but then the same problem occurs on the

inside.This problem started after the upgrade of the backend ecc.

If there is more info needed I would be glad to provide it.

Thank you.
