It looks like you’re running into the Dolphin-028 error, which is a common connection-related login failure in Ubisoft Connect. Close Ubisoft Connect completely (check the system tray). Right-click the Ubisoft Connect shortcut on your desktop and select Run as Administrator.
While general server status for Ubisoft appears to be Operational as of March 13, 2026, there have been some user-reported outages over the last 24 hours (specifically in the US and Israel). If the official status page says “green” but you still can’t log in, the issue is likely a local connection “hiccup” or a cached credential error.

[!NOTE]
If you are getting this error while trying to play The Division 2 or Rainbow Six Siege, it is sometimes caused by the launcher failing to sync with the game’s anti-cheat. In this case, try launching the game directly from its
.exefile in the installation folder rather than clicking “Play” in the launcher.
