Couple months ago Ubisoft decided to make paying customers hate them. Early July they made an announcement for Decommissioning of online services for older Ubisoft games. The link here is to Waybackmachine as original announcement has been updated multiple times.
Quote from Ubisoft:
technology that drove those services becomes obsolete
Ok. I and many others paid for your 15 products. Why should I first send you my money and then wait for you not to maintain servers. Technology becomes obsolete every day. What proper software engineers do, is update and maintain our running software. A decision to decommission Anno 2070 servers was reversed, apparently because the developers felt bad.
Ubisoft: Ask your competition! See how many games others are decommissioning.
Btw. if you didn't know, the technology in question is Java. See Oracle announcement from 2021: Java SE 7 End of Extended Support in July 2022 Obviously it took Ubi, in their infinite wisdom, almost an year to react to the last warning. End-of-life was known years ago. Also, I know moving from Java 1.7 forwards isn't trivial, but it isn't impossible either!
PS.
As Ubisoft is offering their UBI+ trial free-of-charge (subscription will turn into paid one after first month). Currently I have an active UBI+ -subscription, which I'm using to play their games. Obviously I'll cancel before paying. I urged you already in 2020 to take my suggestion: Don't send any of your money to them. I know I won't.
