[Resolved] Cannot connect online

Speaking as someone who troubleshoots this kind of thing for a living, this doesn't seem like a problem with his network. It sounds like pCARS is blocking I/O on the network interface. This is obviously not the intended method of operation.

The only thing I can think of is to try changing your UDP setting. From the ProjectCARS main menu:

- Go to Options & Settings
- Go to Gameplay
- Scroll to the bottom
- Set UDP to "off"

If that doesn't fix it, you've probably got corrupted game files, which is causing the netcode to break, resulting in blocking network I/O. The only option will be to delete the game files and reinstall. Note that you can do this separately from your save data.

I will try turning off the UDP.
I already deleted the game and all the saves, reinstall it, downloaded the latest update and try it again, but the issue continues. So will try to turn off UDP. Thanks

Interesting. I'm really interested to hear the outcome of the UDP setting change.

When you start ProjectCARS and your PS4 goes offline, is any of your other computer network affected? For example, can you still browse the internet through any other devices that are connected via ethernet? Separately, is WiFi affected?

Not, all other devices are not affected. I can still browse with my smartphone or ipad or other computer

UDP is a good thought. A lot of home routers shut down flooding which it could perceive the UDP packets (i.e. if it's a smart router, it would only target the source the flood so it wouldn't affect anything other than the PS4).

^^ This is precisely what I was thinking. Home routing equipment (unsophisticated) might interpret UDP broadcast as an attack (like ARP flood). Many switches/routers will "shut" the port when this is detected.

Hi everyone. I turned off the UPD and works! Thank you very much everyone for your help!

I’ve been having the same issue. UPD is set to Off but still the same issue. It disconnects pretty much as soon as I enter Community Events. So annoying!

Update 28th Feb: Just heard that the PSN is down on quite a few games at the moment. Has been for a couple of days now.
