How Do I Fix Error Code 4b538e50?

I'm sorry that you are having difficulties connecting and playing our game online and I would like to suggest the following troubleshooting steps in order to help you connect to 2K Sports servers:

If you are using a wireless connection to your router, we strongly recommend that you connect your PC via an Ethernet cable as a wired Internet connection is optimal for online gaming. Interference in your local network's Wi-Fi can render your connection unstable and cause issues when trying to connect to the server.

If you are already wired and ready to go, a very simple, but effective step is to reset your router. We recommend that you consult your router's manufacturer guide in order to determine what are the steps required to do so. More often than not, the steps involve unplugging it from the power source and plugging it back in after 30 seconds. Once your local network is back to normal, try logging back into the game.

If, unfortunately, you still cannot go online, please go through our Network Troubleshooting guide:

Check all the physical devices on your network to ensure they are plugged in and powered on.

Perform a connection test on each device connected to the network. For reference, here is a PC troubleshooting guide:
