Is either on the Internet or on the servers of Ubisoft. The best thing is to just wait a while, restart the PC, disconnect and reconnect Wi-Fi and check the rainbow file with Uplay if it doesn't go away.
Sounds silly, but you'd better ask such a question in the Ubisoft forum. The questions often go directly to the development team. Otherwise, always to supporters. Answers often come very quickly. Well, someone described the same problem and got feedback directly. Everything also in German.

No connection to the server.
I HAVE THE INTERNET!
PLAYSTATION 4!
Maybe it just reconnected. Is out with me as well in the morning. Then I have to reconnect. If it doesn't work despite an internet connection, then have a look.
