Issue SSH keys VNC

[killmasta93]

Hi,
I was wondering if someone could help me, Currently added a new host into the cluster and i keep getting the no vnc host verification error


I have tried deleted the key

ssh-keygen -f "/etc/ssh/ssh_known_hosts" -R prometheus
ssh-keygen -f "/etc/ssh/ssh_known_hosts" -R 192.168.3.252

whats odd is that prometheus4 cant see prometheus 2 or prometheus BUT prometheus and prometheus 2 can see each other on the VNC

i was reading on another forum post something about this but not sure if i need to run it on the prometheus 4 which is the new one i added or to all of them??

ssh -o HostKeyAlias=IPv4.address.of.other.node IPv4.address.of.other.node
ssh -o HostKeyAlias=HostnameOfOtherNode HostnameOfOtherNode

Thank you
