To resolve this issue, you will have to connect to the server, and then during the login process, cancel the login when the process has reached either the stage of Connected or Success, by either pressing Escape on your keyboard, or Cancel on the dialogue screen.

Once you have ended the login process at the correct stage, you will pass through a series of prompts, and eventually have the option to select the realm you wish to connect to.
