Solved diagnose problem is network switch loop, after reconnect another port live is back.
Note: HP SPF if you disconnect cable from interfaces module SPF they are still active. Only diagnose another side from switch. When you disconnect SPF insert, then disconnect interfaces on system.
thanks for reply all.

Mind ping is only possible by default if enabled via sconfig >Remote Management

And then only from the same subnet in firewall profile Private or same Domain network.

Leave VMQ and other parameters at default for best performance

I setup VMQ in sugestion on microsoft doc. https://learn.microsoft.com/pl-pl/troubleshoot/windows-server/networking/vm-lose-network-connectivity-broadcom
Firewall now is off. This serwer is a nod on cluster 3 nodes and all firewall is off on time error.
