A&H Waves Card Server turns red as soon as output is routed in SuperR

Hi there,
I already contacted the Tech Support but i post the problem here as well in the hopes somebody has a brilliant idea how to fix this annoying issue

A Colleague of mine works with a Avantis with the A&H Card and Superrack. Everything has been working fine the last shows.
As of today this error startet to show up
As soon as you route a superrack channel output back to the A&H card in the top right overview the server indicator becomes red.
We tried everything. New Cat Cables and even a different server but nothing worked. We loaded old sessions and created a blank session. everywhere the same thing. As soon as an output is routed to the a&h card the server goes red.

Does anyone have an idea?

Regarding the pics. yes i know they are in 48khz but it’s the same with 96 khz. that’a not the issue.
Also it’s no clock issue. it happens on internal as well as digital

regards
