Public-facing Proxmox cluster randomly loses http connection on nodes in a rotating/random fashion

Recently hired, I don't think this is a perfect proxmox setup and would like to improve it.

Currently, our proxmox cluster has its 3 nodes assigned public IP addresses that we use to connect to them. Fairly randomly, we lose http connection to a node(s) and then just connect to one of the other 2. Normally at least 1 node is reachable, but whether or not 1 or 2 nodes are offline is anybody's guess.

To clarify, the nodes are still up and functional, as we can see them when connected to a different one, they just aren't responding on their public IPs.

To make matters a little more confusing, we are blocking pings to the public IPs on all 3 so troubleshooting that has been difficult. I can ping the node that is not responding to public traffic from other nodes using its cluster network IP, but that is expected since its technically still online and the VM's are still online/functioning.

Any guesses or ways to think I could troubleshoot this?
