We have recently had a few questions about how to fix the error message: “Please make sure your network settings are configured correctly. CODE: FDDN533”. Or in other cases FDDN529.
The fix is pretty simple and relates to your, you guessed it, network settings.
There are two fixes you can try.
On the main PES 2017 menu click system settings. Then go into port settings. This should then log you out the server. Turn automatic settings off and leave the UDP port number as 5730. You should now be able to login without any problems.
If the first fix doesn’t work, you can try this one as an alternative.
Exit out of PES 2017 and then steam. Open command prompt (or CMD) and run as an administrator. Within command prompt type “netsh winsock reset” and click enter. Restart your computer, load steam and PES 2017 and it should be working.
