What it means

E2-817B122B is a server connection error on PS5. Sony's steps go from the console to the network and the system: turning it off with the power cable unplugged, turning the router off for at least 5 minutes and updating the system software if it is not current. If none of that works, the code page links to PlayStation Repairs. Each step rules out a temporary console state, a router state or an old version. The code proves no fault.
