Issue Migration issues

[ilijamt]

I'm having issues setting up migration between two different servers of Plesk.

I can ssh from the console to any servers without supplying a key without an issue

I keep getting

Failed to connect to the source server 'source' (x.x.x.x) by SSH: not a valid EC private key file

I've checked the debug logs in the console for the migration session and this is whats in the logs

Does anyone know how to solve this?

If I use username / password for migration there is no issue. But then I have to allow password login for the server.
I've tried using the command line.
And ssh between the machines works without an issue.
