As a workaround use a key with 256 length

  1. Connect to the server via SSH;
  2. Create the key pair

ssh-keygen -t ecdsa -b 256

Generating public/private ecdsa key pair.
Enter file in which to save the key (/root/.ssh/id_ecdsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_ecdsa.
Your public key has been saved in /root/.ssh/id_ecdsa.pub.
The key fingerprint is:
[…]

Copy the key to the Source server:

ssh-copy-id -i /root/.ssh/id_ecdsa.pub root@203.0.113.2

Restart the migration
