vSAN Free 2-node cluster broke after update

[infraanv]

Greetings everyone,

We have a 2 node VSAN cluster on ESXi hypervisors. Today I updated both of them to the latest version available. After both of them rebooted, i cant see the partner appliance from the web gui on both nodes (node A cant see node B, and vice versa).

However, the HA device that they both have is still working, i have a virtual machine on that volume (its a HA volume that i added to a ESXi hypervisor).

Both nodes can ping each other, on the three networks (Management, Data, Heartbeat), so i cant figure out what is actually happening.

I would appreciate some insight on this .

Thank you in advance.

Make sure both are on the same VSAN version.
Remove any from appliances > add it again.
