How can I resolve this error

Are there other members in your party? I would also check if there is any Enforcement Action taken against your account (less likely, as those messages are more direct about being banned, usually, but worth checking). It could be different regions or level
disparity in the playlist that is causing issues?

It's possible that since you moved,
you'll need to update your account and console to the current region. It's possible that since you're across the ocean, your connection to the Central America region is too poor for it to establish and allow a connection?

That looks like a particular game server issue. Im sure when the servers free up this will pass

That error is happening in my halo game

I have 1 month without play halo 5

For that reason

It happens when I try yo play online only

I used to play in central América

But now

I'm living in Spain

Since I came here could'nt play online anymore

I think you need to provide a little more information. Otherwise it'll be hard for anyone to help you with this issue.

Which game is this?

Which mode were you trying to play?

Who were you trying to play with? (Everyone from the same country/region?)

Does it never work? Or only this one time?

I have Just 3 friends in halo

They're in diferent countries
