I am very new to ProxMox. The issue is: We built the Server in our test environment. Then moved it to Stage, this required an IP change. Stage and Test do not have routes to each other. When we spun up another ProxMox server in Stage and attempted to build a cluster we got and error the certificate had the Test environment IP. I changed the IP in /etc/host. Now the IP is correct but the certificate is invalid, when we attempt to a PVE2 into the cluster we get the following error "TASK ERROR: fingerprint not verified, abort!" How do is create a new certificate or update the current one?
