At one point in time, chances are you’ll get an error message that reads: “There was a problem. We couldn’t sign you in. Try again in a few minutes, or check your account by signing in to account.live.com. Sign in: 0x87DD0019.” Despite to what you may think and try, the problem is not necessarily your internet connection, your Xbox One console, or even your account not being in a good standing status. You probably cannot sign in and play online because there is a problem with the Xbox Live network.
Although the Xbox Live network is very reliable, every now and then, you’ll experience the error 0x87DD0019, typically during Thanksgivings, Christmas, New Year, and other major holidays, and when you see this error, you’re likely not to be the only one. When error 0x87DD0019 occurs, it means that there are also thousands of other people unable to sign in or play games because of service disruption because of a problem with Microsoft servers.
It could be because of human error, hardware or software problem, or because of outside forces. For example, back in 2014, the Xbox Live service was under a massive Distributed Denial of Service (DDoS) attack initiated by a group of hackers known as Lizard Squad, which overloaded the servers with bogus traffic from multiple sources around the world, crippling the Xbox Live network.
Although, there could be other reasons involving the error 0x87DD0019 message, it is pretty much guarantee that the problem is on the Microsoft end, not yours. As such resetting your Xbox One console to the factory defaults or home router, or even deleting your account from the console, may not do any good. The only solution here is to wait for the company to resolve the issue on their end.
The best thing you can do is to get inform first. You are likely to find out what is really going on by checking the Xbox Support official Twitter account and by checking the Xbox support web page. If you are having issues, you can contact support on the Xbox forums, though you are likely to get a faster response if you send a tweet to the official Xbox Support account.
Also, remember that a lot of the issues within Xbox can be resolved by powering the console completely off and unplugging the power cable, waiting around five minutes and connecting everything back up.
