You get this error message "Error: The chapter token is not valid: (HTTP 401)" in Transfer Manager while trying to save a file back to server.
If your company uses a firewall such as Zscaler, it can cause this issue because access to our server is blocked. If so please request that your IT department create an exception for the domain *ctrlprint.net.
In rare cases this error indicates a network issue where our server cannot be contacted, such as no internet connection, an unstable network or a security setting.
