  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue Plesk Migration Fail to connect servers together

New Pleskian
Server operating system version
AlmaLinux 9.5 (Teal Serval)
Plesk version and microupdate number
Plesk Obsidian 18.0.68 Update #2
Hi, I have a VPS in OVH with Plesk Obsidian and a dedicated server with OVH again with the same version of Plesk. I'm trying to move everything from the VPS to the server with the Migration Tool but I have this error:

Failed to check SSH connection to the source server 'source' (X.X.X.X): Unable to connect to 'X.X.X.X' by SSH: Authentication failed..Ensure that the server is up and there are no firewall rules that may block SSH connections to the server, then restart migration.

I didn't add the SSH Key because I have the root password, also I checked the password and it's correct. Both VPS and server have disabled the Firewall.

What I have to do?

This error is typically caused due to incorrect root credentials. Are you able to establish an SSH connection from the destination server to the source server manually by using the same root password defined in the Migrator?

Thank you but I checked the credentials and yes there are correct. Yes I tried the SSH connection directly and she all good. Firewall disabled but not working :(
 
Usually root access is not allowed by default over SSH, it is something that needs to be enabled. When you testing your SSH connection, are you doing it from a terminal or using OVH's built in tools for making the connection and then logging in as root? And if through an actual terminal, are you using root@IP or a different username?

I tried by OVH terminal with root@IP and I also tried via Plesk built in tools. I don't remember if I had to enable root access via SSH 2 years ago on the VPS. But it's working.
 
Could you please double-check the SSH logs on the source server for entries with the target server IP? If it's Almalinux, please try:

cat /var/log/secure | grep target-server-ip
