An error occurred during communication with the server

If you get this error if you ever want your PS3 to read disc ever again you will have to send it into Sony for warranty, and if it is out of warranty you will have to pay 150.00 for them to fix it.

Go to Settings Settings in your XMB and change both the primary and secondary DNS to 4.2.2.1, and if that does not work set everything to automatic.
