Describe the bug

When trying to fetch from this repository, git gives errors and when "fixing" those, it doesn't use the configured ssh key.

To Reproduce

$ git remote add kieran git@git.v0l.io:Kieran/snort.git
$ git fetch kieran 
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @

The ECDSA host key for git.v0l.io has changed,
and the key for the corresponding IP address 2001:41d0:203:d372::
is unknown. This could either mean that
DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time.

It is also possible that a host key has just been changed.

Add correct host key in /home/leo/.ssh/known_hosts to get rid of this message.

  remove with:
  ssh-keygen -f "/home/leo/.ssh/known_hosts" -R "git.v0l.io"
ECDSA host key for git.v0l.io has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
$ ssh-keygen -f "/home/leo/.ssh/known_hosts" -R "git.v0l.io"

$ git fetch kieran

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

git@git.v0l.io's password:

So I am confused here. The first git fetch kieran yields a different server key than the second:

  • 1st: SHA256:pCQ3ssyCMVQVmZszz8mMA/8eH8mGgZPmpIo72JL3GTs
  • 2nd: SHA256:erhTvN6QdZk/19GFKpTKs4RyS8ocYER6yTfb3YNgIXc

and directly running the same command again, I get:

$ git fetch kieran
