Unable to join session and communication with xbox live servers has been interrupted.

Hey Syd, sorry to hear about the connection issues! We're happy to help, but let's try a couple things right off the bat. Can you please try resetting your network hardware by unplugging the power cables to your router and modem for about 15 seconds each?
After that, try running a LIVE connection test, to see what comes up. Please let me know how it goes!

Hey there!

Unfortunately each situation can seem similar, but the difference can be in the the details (model numbers, hardware type, etc). Having specific detailed information like that actually helps us solve most of the network issues reported on our forums.

We do have a separate forum for known network issues for many home network devices. Check out our Networking Hardware Information forum and see if your device is listed, but in order
for us to continue troubleshooting we will need your hardware information. Please let us know when you are able to provide your hardware information so we can look into this issue further.

Thanks!

You have no need to know the specific make and model of anyone's router and modem. Let's just say it's a fairly common hardware configuration. If there are makes and models of specific routers and modems for which known issues exist, why not save everybody
a lot of time and post those issues?

Simple fact is that 99.9% of Xbox Live issues have nothing to do with the consumer endpoint. Most likely, it's poorly written code that doesn't allow for graceful termination of previous connections.

Hey there Wizard231!

I'm sincerely sorry to hear about the Xbox Live issue! What is the make and model of your router as well as your modem? Also could you list any troubleshooting steps you have tried so far? That information will help us out a lot!

Post back with the information and we will do our best to help get this sorted!

Hello there @Ep1cLunchBox, I hope everything is going well!

Thank you for reaching Microsoft Xbox Forum support. I want you not to worry about the situation because I am here to help you out! I believe your console might need either a network reset or just a system refresh. I would like you to go through the following steps to clear the Mac address and then perform a quick power cycle on your console:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console.

Another thing you should check is your NAT type. I would like you to check your NAT type if open because that could sometimes interfere. to check for the NAT type you can follow the steps below:

Settings > Network Settings > NAT type => It should be open.

If the NAT type is not open, you will need to open some ports with your internet provider. 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).

In case the issue still persists after the previous steps have been performed here is the official link to all the network troubleshooting steps that can help sort this out for you.

In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.

I wish you a lovely day, and I hope this helps you out! All the best!

Kind Regards

Stay safe, and happy gaming!
