Hello,
I'm having trouble adding a host to cockpit.
It was already listed in cockpit but then I reinstalled fedora on it, removed the host from cockpit and now I get the following message when I try to add it again:

Incorrect Host Key
The key of myhost.mydomain does not match the key previously in use. Unless this machine was recently replaced, it is likely that someone is trying to attack your connection to this machine.

How can I solve this?

Thank you.
F.
