  • Applies to:
  • Plesk 11.x for Linux
  • Plesk 10.x for Linux


After data transfer from Parallels Plesk Panel 10.x to Parallels Plesk Panel 11.x, the panel on the right may be loaded with an error about an insecure response or a refused connection (depending on the browser used).
The error occurs when the following options are used for the transfer:
- “Skip global server settings and system services configuration”is switched off on the “Migration Settings”screen.
- Remapping of IPv4 addresses to IPv6 addresses and vice versa are selected on the “Define IP Addresses Mapping”screen.


This error is connected with an SSL certificate that was updated during the data transfer.


Logout from Server Administration Panel and login again.
