Hello Stephen,
Thank you for the clarification.
This “Sign in” button is meant to sign in to the RU Server, so you would only need to use it if you have the RU Server authentication set up on your remote Host.
Please try right-clicking the target Host in the address book and selecting
Log on or selecting the
Full Control connection mode in the toolbar and double-clicking your Host s described
here.
Let us know if this helps.
