A quick little tip for the future…always check here: Online Services Monitoring as well as in News & Announcements 
any issues are always posted there so always have a look!
If possible, I would also recommend changing multiplayer servers as well. However, this doesn’t seem to be the case for you.
If you have done that and you are still having issues, Is Online Functionality On?
(Options > General Options > Data)
Best of luck to resolve your issue, and let me know please your results!
Cheers!
