Connection to Zeus Backend has been lost (and crashing)

I’ve been having problem with my VU Server for the past 6+ hours.

Everything worked perfectly today with 64 players joining my server. Then suddenly things started going south.

My server (Vu.exe) has been crashing a lot, i have like 8 DMP files to be examined (by who?)

Now - when running the server, the connection to Zeus Backend fails every now and then, which results in all clients dropping out.

Firewall and Microsoft Defender is properly configured to allow VU - so i dont understand what is going on.

VU Client also has problems connecting to Zeus ?!
