Try changing the DNS on Xbox One.

Use Google.

The Google Public DNS IP addresses (IPv4) are as follows:

Primary DNS: 8.8.8.8

Secondary DNS: 8.8.4.4

After changing, restart Xbox One.

It worked for me.

Ports required to use Xbox Live

These ports must be open for Xbox Live to work:

• Port 88 (UDP)
• Port 3074 (UDP and TCP)
• Port 53 (UDP and TCP)
• Port 80 (TCP)
• Port 500 (UDP)
• Port 3544 (UDP)
• Port 4500 (UDP)

Note Some game developers require you to open additional ports. You should always check the game developer's website to see if the game you're playing needs additional ports to work. We've gathered some ports you might need
and have added them to the
Additional Network Ports for Multiplayer Gaming forum.

If you're connected to a network through your workplace or school, ask the network administrator to open these ports.

If you receive a NAT warning when you connect to Xbox Live, see the

Have you tried to hard reset the console? Another option would be is to factory reset the modem; if you have rebooted it already.
