@cpt-wenchbane Having the same issue as well since at least yesterday.

@cpt-wenchbane For me it doesn't seem to have hampered my ability to play other online games, I tried to disable my firewall and also reinstalled the Ubisoft Connect app to no avail.. Looking through the forums it seems to be a recent issue with other people as well.

Hello, I've finally fixed this issue..

1. What I did was try to create a new account through the Ubisoft Connect launcher, it created the account but was giving the same error when trying to login.
2. I then opened the launcher again, and then check marked the start in offline mode.
3. I closed the launcher after, it wouldn't start in offline mode but after entering the new account details I was able to login successfully.
4. I logged out of this new account, and logged into my main account successfully.

I hope this helps anyone struggling with this issue, not sure if it's a fix for all but it did for me.

@kingteranas I guess a ubisoft support rep replied to this one saying to try to reinstall the app which I did with same result - https://discussions.ubisoft.com/topic/105958/a-ubisoft-service-is-unavailable-please-try-again?lang=en-US
