Error Code: 40010000

Hi, can I check a few things?

1. Have you played the game on another PS4? No
2. Does more than one account play the game on your main/home PS4

No
3. If yes to 2, do those players have their own PS Plus subscriptions or is your one shared?

I have 1account and thats the only one, and this Ps4 ive got at home is the only one i play at.

Im not so keen on reinstalling the game and loose all my progress sice ive finnished it all, collected all collectibles and at level 50+ 😂

Error Code: 40010000

I've Reset My Game Multiple Of Times.

Same here. Got the exact same code and I play on the PC.

Gotta love being forced to connect to online services and store on cloud servers.

Fix for me was to upgrade all my cars in solo mode. Edit license plate text or swap some parts for every car. Then quit to lobby. It shouldn't show the error code anymore when it loads to the lobby. After that I exit the game with Alt+F4. (Did not work just connecting to online straight up) Started game again no error codes and could play online again.

Trash fix 

So did anyone ending up figuring out what’s going on?

I'm still having this problem.
