Hey there,

Is there a specific error code that you get with that error message? It sounds like there may a network issue, or there may be other software installed on your Windows 10 PC that may be interfering with connecting to the game's servers. To start, let's try
uninstalling and reinstalling Minecraft: Windows 10 Edition from your Windows 10 PC. You can uninstall Minecraft from the app list within the Start Menu on Windows 10, and reinstall the game through the Windows Store.

Hope this helps!

Hi,

The 'DHCP server' is part of your router or internal network you're attempting to connect to, nothing to do with the Internet or Xbox Live. The normal process when you turn on your console (or any WIFI device for that matter) is that it connects to
the router and, in a manner of speaking, asks the router for a unique internal IP address to connect to the local network and thus, the Internet.

This network access request is handled by the router's DHCP (or Dynamic Host Control Protocol). It's called a 'server' because in large networks a dedicated machine may be assigned to handle the issuing of network IP addresses, hence the confusing
name. Many people get confused with DHCP and assume it's something outside of their own network.

Most of the time this process works automatically. Sometimes however, DHCP has a conflict and tries to assign an IP address in its range to a device, that is already being used by another device. Each device (and when I say 'device', I mean anything that
can connect to your network wired or wirelessly) needs it's own unique IP address. If, for what ever reason, your console can't connect to the network due to an internal IP conflict, the usual error is a DHCP one.

If you're sharing an Internet connection with multiple people - like in college or university dorm - you may need to contact the network admin for more help. DHCP is a networking error, it's not a console error.

Hope that makes sense.
