Error Code: 80710723???

"An error has occurred. You have been signed out of PlayStation Network. (80710723)"

My internet connection with my PS3 is at 100%... And I was just about to go on Call of Duty 4 online, but didn't get the chance to... So can someone explain why this happened and what the cause was? :?

i had it alot what i did was unplug my router and plug it back in sign in and it should work that way i think it has something to do with the connection VaughaneyD

I just sign in again and see what happens.

From Playstation.com US forums:

80710723 Possible Port Error - Try opening ports , TCP port: 80, 443, 5223 and UDP port: 3478, 3479, 3658. or add Ps3 to DMZ

You really might want to try creating the connections again on your PS3 system on the same modem/router you are using.

this same thing happend to me but it was slighlt different. I was trying to downlaod c&c red alert 3: commanders challenge and it kept giving me the same error code as you. I did some searching and found out that 1. it only affects big downloads (2gb) 2. and it only happened to people with qwest internet and WIRE2 routers so my only question is do you have qwest, I do :(
