new server, same ip, wont ask about RSA fingerprint

[theworm4002]

had to replace a server and assigned the old server's URL / IP to the new server. attempted to connect to the server (site) and just got "unable to connect to the server" it didn't ask to accept the server's RSA fingerprint. I removed the server (site) and made a new one but there was no change when I clicked connect.

Connecting to: server2.ovh on thread: pool-9-thread-1
New wrapper session
