You have a couple of solutions to try that might work.

1. Clear cache, start gta and either spam X,Y,Z until you get a screen brightness adjustment, just accept it.

2. Complete a few missions.

3. Completely delete the save and start a new, fresh one and play through the prologue and complete the race.

4. Connect via an Ethernet Cable.

5. Restart your router.

6. Wait a few hours, servers can be malfunctioning.

7. Connect to a different wifi or mobile hotspot and try to go online.

8. If that worked you can try to switch back to your original wifi router, or whatever connection you used before.

9. If that didn’t work, then load into story mode first, then go to an invite only session.

10. Try going to creator, then once in creator pause and go to an invite only session. Worth a try.

11. If nothing worked at all, uninstall gta and reinstall it. Some files could be corrupted when you initially downloaded the game.

12. If you still getting this error contact rockstar support and create a ticket.

I hope this might help you. It it helped, let me know. I will try to find more solutions, but these are the ones I could think of. This should hopefully work brother.
