Hello guys, i have next issue:

PC 1 with
• 3 vmix calls for the 'talents';
• 1 vmix call back-up;
• 1 DANTE input with audio pgm for return;
• 1 NDI input with video pgm for return;


PC 2 with
• 2 vmix calls for the 'casters';
• 1 vmix call back-up;
• 1 vmix call for the winner interview;
• 2 DANTE inputs, 1 audio pgm for the casters and 1 audio pgm for the interview;
• 1 NDI input with video pgm for both.

So the issue happens random ( imo and other teammates).
Once in a while ( happened 2 times in 20mins and then didnt happen for like 2-3 hours until the broadcast ended ) the vmix calls and dante input/s freeze (just audio) for like 2 seconds then everything it's 100% normal except the dante input/s who it's stopped. I have to go change and re-add the exactly same input (channels).

To avoid some questions.

•Both pc's have 3 nic's.
-Enthernet with his own vlan;
-NDI with his own vlan;
*Those 2 are in the same switch (arista switch, idk the exact model rn)
-DANTE with his own vlan ( Cisco switch, idk the exact model rn)

If you have any other questions about the production let me know. Thank you all

This sounds to me like a network issue. Please check the switches are on the latest firmware. It isn't 100% clear to me why you use different switches for different VLANs. Usually a switch can handle mny VLANs.
Please update the NIC drivers to the latest. Is it 10G. Windows 10 and 10G can have issues. Please update to latest as well. The 10G issue isn't present on Win 11.

If the issue still persists log the traffic with Wireshark and troubleshoot from there.
