CWP -> CWP Connection not reached

I looked in forum for an answer but could not find it. Our problem is the error: Connection not reached While connecting to migration. Firewalls are down so no limitation, ips are in whitelist, know hosts etc. We can migratie any server we want but except this one. Any ideas on how to debug why this "Connection not reached" error can be solved? We can SSH to the migration server just fine. So looks like the tool just does not start or connect. Please any advice?

SOLVED! We found out that ssh needs to have "PermitRootLogin yes"

Could you make your solution a little clearer? Not 100% sure how to go about "PermitRootLogin yes"

Thanks for help!

Forget my question, had brain lock.
