• When connecting to ports 22 or 21 (Plesk Website Importing tool) on the source server using the telnet utility, the connection fails with:

  # telnet 203.0.113.2 22
  Trying 203.0.113.2...
  ...
  telnet: connect to address 203.0.113.2: Connection timed out

Cause

Connections to ports 22/21 are blocked by a firewall on the source server.

Resolution

Make sure that firewall settings on the source server allow connections via TCP ports 22/21.

If the issue still persists after opening both ports locally on the server, contact your service provider to find out where the connection is blocked.
