error:0A000086:SSL routines::certificate verify failed (596)

Hello, I'm trying to set up a proxmox cluster of two nodes on Hetzner dedicated servers, with the communications passing through a vSwitch.

The IPs of my nodes are respectively and, and I had a hard time to get the second node to even join the cluster because it kept saying the fingerprint wasn't valid, but when I made it join from SSH using pvecm add it joined successfully.

The problem now is, when I go to the first node's web UI and I try to access the second node, I get the following error:
Connection error 596: Internal Server Error

When I go to the second node's web UI and I try to access the first node, I get another error:
error:0A000086:SSL routines::certificate verify failed (596)
I was able to fix the certificate verify failed by rebuilding the certificates on both nodes, and now if I log in to the second node's web UI I can access both nodes, but from the first node's web UI I still can't access the second node, as it still says Connection error 596: Internal Server Error
Sometimes it doesn't say Internal Server Error and instead it says connection timed out.
Out of curiosity did you ever sort this out? I'm having a similar issue after changing the hostname of a node.
