Transfer tool error from WHM 110(Redhat Enterprise Linux V7.9 OS based) to WHM 114 (Almalinux 9 OS based)

Hello community! I'm trying to transfer account from my old cPanel to new one. The old is running Red hat Enterprise Linux V7.9 and WHM v110.0.12, the new one is Alma Linux v9.2 and WHM v114.0.7. I'm trying to transfer one account at a time, just for test, to get it to the new server. but planning to do transfer for multiple accounts. SSH access through ssh clients like (csp,putty,teraterm) to both servers is passing without error. But, when attempting to connect via SSH from WHM using root(default) and password from the new server to the old server, the transfer tool is giving this error: The remote basic credential check failed due to an error (The password that you provided is not correct, or the SSH key is not permitted access: Cpanel::OS::Linux does not implement sudoers at /usr/local/cpanel/Cpanel/SSHControl.pm line 86. ) and response:
  • ssh transport failed (The remote basic credential check failed due to an error (The password that you provided is not correct, or the SSH key is not permitted access: Cpanel::OS::Linux does not implement sudoers at /usr/local/cpanel/Cpanel/SSHControl.pm line 86. ) and response:); trying whostmgr "
  • whostmgr transport failed (SSL connect attempt failed error:0A000086:SSL routines::certificate verify failed); no more transports to try.

I have root access to both VPSs, I turned off the firewall on both servers and i have permitted RootLogin and PasswordAuthentication in sshd_config on both VPSs. I don't have Host Access Control set up on either server. I have disabled cPHulk, But i am still having the error. Note that the transfer tool can connect from old server to the new server but can't connect from the new server to the old server. Any suggestion on how to solve this issue?

    Hey there! I know you mentioned that SSH works *to* both servers but for the Transfer Tool, you'll need to ensure the access works *between* the two servers. If you connect to the Destination server and just try a basic "ssh root@source-server.com" does that allow you to connect, or do you receive the same error?

    Thanks for your quick reply @cPRex, YES, the basic "[COLOR=rgb(235, 107, 86)]ssh root@source-server.com" works without error between the two servers. But with the transfer tool in the new server, it gives the indicated error. i have googled everywhere so far, but i didn't find yet someone who may has already encountered the same error.

    No one has faced the same issue before ?

    It doesn't make sense to me that the manual SSH connection would work, but Transfer Tool would fail, as we just use an SSH connection between the systems. Here's a test you could try - can you make sure port 2087 is open between the two machines? A simple 'telnet x.x.x.x 2087' would let you know if that is open (you may need to install telnet if that command isn't present)

    port 2087 is open between the two machines. This is checked and confirmed by using 'telnet x.x.x.x 2087' on both servers. on the other hand, i am still not understanding well the error which the transfer tool is giving and why. i don't know if there is no compatibility between the 2 servers at OS/applications(cpanel/whm) layer for the transfer tool to work normally.

    At this point, it's likely time for a ticket so we can investigate why this isn't working directly on the affected systems.
