GTA V on Xbox one only online in solo mode playable?

Can someone help me please?

I've recently got an xbox one S and bought GTA V, it's all great but unfortunately, if I want to play GTA online, I can only play in solo mode.

If I want to play with other players it always loads too long and then comes the message:

An error occurred while joining the session and then I return to story mode.

I already have a social club account and an internet connection.

Please help me

Has done, console restarted, now everything goes, I'm just sooo happy
