Error saving configuration

[Varlin]

Hi all,

I've encountered an issue I've not come across before and wondered if anyone on here knows of a fix.

When trying to save a configuration back to a system using Manager the following error message is displayed -

Failed to save the configuration data
(Unable to read data from the transport connection. An existing connection was forcibly closed by the remote host)

The system has been rebooted which has not solved the issue.

Have confirmed that changes can be saved back to the system using web manager

The IPO is running R9.1.8 software.

Thanks in advance
