  • Applies to:
  • Plesk 10.3 for Linux/Unix
  • Plesk 10.3 for Windows


  1. I had stand-alone Plesk Billing 6.0.3 with Paralles Plesk Panel 9.5.4 (see attached).
  2. I have upgraded to the Customer & Business Manager 10.3 and the remote Parallels Plesk Panel 10.3.
  3. I try to reconnect to remote Parallels Plesk Panel in the Customer & Business Manager to log in to Plesk Panel. 
Parallels Plesk Panel reports the error, "Failed to find XML nodes by XPath 'get_protos/result' relative of server." I can't log in to the Parallels Plesk Panel, because of cyclic redirects between Parallels Plesk Panel and SSO relay.


After the upgrade of remote Parallels Plesk Panel to version 10.3, you should install a valid Parallels Plesk Panel 10.3 license. After you have installed the valid license, you will be able to reconnect to the Plesk Panel in the Customer & Business Manager, and perform the transparent login.
