That error code references to a networking error. You should try to reboot your router or cable modem by unplugging the power cable for about 10 seconds and plugging it back in.

If your problem persists, check out this page and compare your results below..

Gameplay:

Ping < 50: You should be just fine

Ping > 50: May notice slight lag occasionally

Ping > 75: You will notice lag

Ping > 100: It will be very hard to play online

Ping > 125: It will be extremely hard to play online

Ping > 150: You will be very lucky if you can even find a match

Video streaming (like Netflix)

Download speed is what you really need for this, and your ping is dependent on this as well. If you have a good ping, you should be fine. If not, you should check your download speed and compare it to the app's requirements.

.

If your speeds are bad, you should consider calling your ISP (Internet Service Provider) about the issue, they will usually optimize your speeds for you to stop the problem.

I hope this helped solve your problem, and I would love to hear back from you.

Good luck!

Same problem here with the same error message. All my credentials are correct and I have a 60mbps connection.
