One user’s Reddit post reported, “Ubisoft Connect for PC is currently down… Currently unable to log in or start game on PC… Error dolphin-028.” This is how you can fix the Ubisoft Connect Dolphin-028 error on Windows PCs.

Check for Ubisoft Server Outages

Set Ubisoft Connect to Run as Administrator

Running Ubisoft Connect with elevated privileges (admin rights) is a troubleshooting method some players confirm can remedy the Ubisoft Connect Dolphin-028 error.

2. Click Run this program as an administrator to select the checkbox for that setting on the Compatibility tab.
