I have this problem too sometimes, I can't connect to matchmaking yet my brother's account can. The way I fix this is just to reset the PS3 and internet, and make my PS3 the Primary connection to the internet (every PC in my house is wireless and I have a dynamic IP)
Its my brothers account that he uses on his ps3 it wouldnt not connect to it on his so we tried on mine and it didnt work but my account is working on mine.
