Suddenly ESXi disconnect to Veeam

[SerSunal]

I have connected a new ESXi host to VBR. But after configuring some things on the virtual switch, it stopped having a connection with VBR and can no longer connect. My question is if there is any configuration that can be modified in the ESXi virtual switch on the Administration network that will make it disconnect from VBR

can you test by doing ICMP from VBR server to the ESXi?
