Cannot connect to MP Lobby Service

When I attempt to join any MP game type, Arena, Warzone, Custom, it keeps getting an error “Attention: There was an issue with the Halo 5: Guardians Servers. Please try again.” I see others can connect, so what can I do to reset?

Thanks!

Never mind - starting a different game and then restarting Halo, fixed it.

I’m having similar problem over the last 2-3 days
After the big Xbox One update I am no longer able to connect to lobby services (“Attention unable to connect to the halo 5 guardians lobby services”).

(1) I have rested / hard reseted both Xbox and router
(2) I have added halowaypoint.com to the allowed sites
(3) I have even changed regions and languages as some kind of testing

Still no luck:(

I hope anyone can help with some sound advice or 343 can patch it up really quick

Having same issue right now. Was playing then all of a sudden got kicked out of the lobby and now can’t connect. Been a couple hours now. Pretty annoying.
