Cause

Issue in the product.

A fix is planned for C21.12 (ETA December 2021).

Solution

This issue has been fixed in C21.12, please update Cyber Files Client for Mac to the latest build. You will need to re-login after installation.

As a workaround without updating, delete the keychain entry and then log in again:

• Find the entry com.acronis.filescloud and delete it
• Start the Cyber Files agent
• Open Preferences and log in: enter username, then log in through the Login page.
