Error Dolphin-028: How to Fix the Login Error in Ubisoft Connect

In the last few days, there have been countless reports of Error Dolphin-028 when signing into Ubisoft Connect. The error message reads, There was an error during your login to Ubisoft Connect. Please restart your client and try again. (Error dolphin-028).

Before you proceed to the slightly complex solutions, restart the PC, terminate any conflicting processes (including GoodbyeDPI), change the Ubisoft account password, and switch a mobile hotspot instead of using a Wi-Fi or LAN connection.
