Issue

You are trying to apply a trusted certificate for your Acronis Cyber Files Server but receiving the following error:

Failed to export temporary certificate store (Key not valid for use in specified state).
Failed to save settings for Acronis Cyber Files Server.

 

Cause

The key was not marked as exportable when it was imported using certificates.msc. This is why we cannot export it.

 

Solution

Check the Mark this key as exportable box when installing your certificate to your Windows certificate store. Please refer to this step-by-step instructions for more details (see step 15).
