I came across this PSN error code recently and when I searched for the code I couldn't find it online or on the Sony Playstation help website. There were some posts on Reddit but with no answers to their questions. Some people were very frustrated that they might have to give up their accounts and all the inventory, coins, progress, that they had on that account. Every account on each game when attempting to play, either said WS-44750-0 or it said unable to connect to Playstation Network, when I knew I was logged into the PSN.
So I restarted my Playstation, and held the reset button on my Router, which it then rebooted, didn't work but you have to try this step first. So then I went back into the account and signed out of the Playstation Network on that account, and directly went to changing my account password. Hopefully for others they have all their PSN account information written down because you'll need the 'B-day' that you set the account up with, to reset the password. I did have all my information and I reset the password to the account, logged back into Playstation Network and I was able to start gaming again. It worked. Now I will reset each account password if need be.
Hopefully this helps others,
Game On!
