upgraded NIC to 10 gbe, now web client is not reachable

[twashington17]

I have ESXi 7.0u3 on a a HP Proliant DL380p Gen8 server. I swapped out the 4 x 1 Gbe mezzanine NIC card for the 2 x 10 Gbe mezzanine NIC card. The problem is suddenly the host is not ping-able and it's web client is not accessible. Oddly, I can ping out from the host's console UI successfully. In addition, the VMs on this host are successfully running and accessible and vCenter can reach the host and it's manageable/configurable like normal via vCenter's web UI. I still use the host's web UI from time to time and I need the host's IP address to be ping-able since it I have apps that ping it to make sure it's up and running. How do I troubleshoot this?

look like its driver or firmware issues . please put back old one card and check all drivers there , if no install new card drivers, once confirmed then replace it with new card and check firmware and drivers must works. please check network setting before changes so u aware all path of networks.

Awesome! That was the problem (duplicate MAC addresses). Thanks!
