Now I know that the error occurs when it adds the "Team" to the Hyper-V Virtual Switch (no difference or is on SR-IOV or not), so it's happening on both servers.
What is the solution? To eliminate the error.
The problem is when it is on (in virtual switch seetings - extensions):
Microsoft Windows Filtering Platform
(WFP vSwitch Extension LightWeight Filter for Hyper-V Virtual Switch Filtering)
for Type of external network
After disabled the problem disappears.
Also on another LAN card (another Intel model),
but not tested for LAN cards from other producer.
