Online map loads but no players are in my game nor can I join anyone -

[ThexKezza]

When I load GTAO I'm put in a lobby with no players at all, I get "Unable to connect to sesson" when trying to join friends, they get the same when they try to join me.

What I have tried:
- Resetting internet(Unplug router for 30 seconds then plug back in).
- Friend downloading my profile and trying to go online - He was able to go online using my account, but I still can't.
- Made new character - Used wired and wireless to try and connect
- Joining friends (vice versa)

Details:
- Nat Type: Type 2 - Playstation 3 (slim) (Top slide disktray)
- My brother owns an Xbox 360 and can get online with a populated lobby with no issues.

If anyone has any ideas please post, or just leave a reply if the same thing is happening to you. Rockstar seems to be almost completely unaware of this problem because I have seen nothing mentioned about it by them anywhere.

Thank you.
