Help with pushing new version of script

[Diggington 20]

Hey,

I need to fix one of my scripts on the SDN, but when I go to push a new version I receive the following error:

git push origin master
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The ECDSA host key for ssh.dreambot.org has changed,
and the key for the corresponding IP address 143.198.12.24
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.

  remove with:

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I'm not super familiar with git so any help would be appreciated. I tried some solutions from StackOverflow but couldn't get it working.

Thanks

Looks like Dreambot have rotated their SSH host key and you'll need to remove the key from your known_hosts file.
 

You can remove the third entry (non-commented line) from /home/XXX/.ssh/known_hosts as shown by the line in the above output:

Offending ECDSA key in /home/XXX/.ssh/known_hosts:3 (Note: - The :3 identified the third line)

Or alternative, as the message suggests you can run the command to remove that key automatically

 remove with:
  ssh-keygen -f "/home/XXX/.ssh/known_hosts" -R "ssh.dreambot.org"
