I tried to connect to a clients ftp via SFTP (port 22) today but got the error message by winSCP that the host key from remote differs from the locally stored key.
The last login is a few month ago but the hoster said they didn't change the machine in the meantime (and I didn't get an error message back then). Fortunately they communicate the host key of the server and it is indeed the suggested key from the winSCP error message.
Sounds like there's no problem, but I would like to understand why winSCP - although obviously nothing changed - doesn't seem to have the right key. I tried to read out the key in an ini export to compare it to the current key but the keys are encrypted.
Any idea what could be the reason for this behaviour?
