Error CE-34878-0

Hello,
Been playing D2 res., since last year, did not got a single error.
When I started playing Ladder, then it began.
First: When using tp scroll to town in act2 severs- this error., but no where else.
Now: every time I use a tp to town 2 times- nothing, 3rd time= error, no matter the place. Tried to update and every other thing, reinstal the game still same problem, initialize PS4- still nothing- same same problem.
SO please, if anyone had the same issue, please respond.
Thank you
