Not much to go on but initial guess is your vSwitch isn't failing over properly.
What is your teaming policy and settings?
A few things to try: - Try manually pinning vmk0 to vminc1, and verify whether the server is still reachable. That will rule out the Meraki side switchport config etc. - With the vmk0 pinned to vmnic0, try removing the cable on vmnic1 and verify whether the UI shows the link as down. If you have VM's, you can also verify that any that were connected to vmnic1 have successfully failed over to vmnic0 - Ensure that your NIC drivers on the server are up to date.
Only configure Meraki lag if you are using 802.1AX/802.3ad LACP protocol on your NIC Team. If you are just using regular load balancing and not running the protocol then you will do more harm than good. Then you should just keep your switchports separate. In that case also make sure you are not load balancing based on destination IP or L4 info because that will cause severe MAC flapping on your switches.
