Frequently Asked Questions

What does NBA 2K error code 2K-EFEAB30C mean?
Error code 2K-EFEAB30C means that your game lost its connection to the NBA 2K online servers. This can be caused by a 2K server outage, your local internet connection dropping, a strict NAT type, or network configuration issues on your router or device.
Is NBA 2K error 2K-EFEAB30C a server problem or my problem?
It can be either. Start by checking the 2K server status at support.2k.com or Downdetector. If the servers are reported as down, it is a 2K-side issue and you must wait. If the servers are up and other players are online, the issue is likely on your end and the troubleshooting steps in this guide should help.
How do I fix error 2K-EFEAB30C on PS4 or PS5?
On PlayStation, start by closing the game fully and restarting your console. Then go to Settings > Network > Test Internet Connection to check your connection and NAT type. Power cycle your router, switch to an Ethernet cable if possible, and change your DNS to 8.8.8.8 / 8.8.4.4. These steps resolve the error for most PS4 and PS5 players.
How do I fix NBA 2K error 2K-EFEAB30C on Xbox?
On Xbox, quit the game fully, restart your console, and run a network test under Settings > General > Network Settings. Make sure your NAT type is Open. Power cycle your router, use a wired Ethernet connection if possible, and set your DNS manually to 8.8.8.8 and 8.8.4.4. Also make sure UPnP is enabled in your router settings.
Will I lose my MyCareer or MyTeam progress if I get this error?
In most cases, no. NBA 2K stores MyCareer and MyTeam progress on 2K's servers, so a temporary connection error should not erase your data. However, any unsaved progress from a session that was interrupted mid-game may be lost. Once the connection is restored, your previously saved progress should load normally.
