can't deploy with SSH in CI

[joepio]

I updated to a new server some time ago, which means I had to update my key and IP address, too. I suppose my github secrets are misconfigured.

I've tried:

• setting REMOTE_USER, REMOTE_HOST and SSH_PRIVATE_KEY again
• Create new SSH keypair using RSA (previous was OPENSSH)
• Other / older version of github action easingthemes/ssh-deploy@v3 (could be it, see issue)
• Manually adding key to server... Worked!
