Failed to resolve the server address Check your DNS settings and try again

It could well be a problem with your ISPs DNS servers.

Try to work your way around this problem by configure your Xbox DNS settings so that your console resolves names into an IP address by using a public or open resolver.

Configure Googles public DNS servers as the primary and secondary DNS under your consoles network settings.

Try specifying dns server addresses of 8.8.8.8 and 8.8.4.4 on your console- These are Googles Public DNS Servers and might resolve your issue

If you are experiencing a "connection refused" error when trying to connect to a Minecraft Java server, there are several potential causes and solutions.

1. Check server status: First, ensure that the server is online and running. If you are not the server owner, check with them to confirm that the server is running and that you have the correct IP address and port number.
   
2. Check firewall settings: If you are hosting the server, check your firewall settings to make sure that the port used by the server (default is 25565) is open and allowing incoming connections. If you are connecting from a different network, check that the network's firewall is not blocking the connection.
   
3. Check server settings: If the server is running but you still cannot connect, check the server settings to ensure that it is configured to accept connections from your IP address. If the server is set to only allow connections from certain IP addresses, make sure that your IP address is on the list.
   
4. Restart server and/or client: Try restarting both the server and your Minecraft client to see if that resolves the issue.
   
5. Use the correct Minecraft version: Make sure that you are using the correct version of Minecraft to connect to the server. If the server is running an older version of Minecraft, you may need to switch to that version to connect.
   
6. Use a different DNS server: Sometimes, the DNS server you are using can cause connection issues. Try using a different DNS server or resetting your DNS settings to see if that resolves the issue.
   

If none of these solutions work, there may be a more serious issue with the server or your connection. You can try contacting the server owner or your internet service provider for further assistance.

In that case, let's try a few things. First, follow these steps:

1. With the console on, press and hold the Xbox button on the console itself until it shuts off.

2. Unplug it from the wall for 30 seconds.

3. Connect it to wall again.

4. Turn it on.

5. Try to run the game and see if the issue has been resolved.

If the same issue keeps happening, try to change the DNS address on your console. Go to Settings > General > Network settings.

Select Advanced settings from the Network screen options.

Select DNS settings.

Select Manual.

Enter the DNS settings. (8.8.8.8 for the primary DNS server and 8.8.4.4 for the secondary).

Restart your Xbox afterwards and check if the game works.

Alrighty! Kindly also try clearing your MAC address. Go to your Xbox Settings. Select Network Settings > Advanced Settings. Under Change Settings select Alternate MAC Address> select Clear. Allow the console to restart when prompted then try to launch the game again.

If that did not work, try changing your DNS. Go to Settings > Network > Advanced Settings > DNS settings > manual

Primary DNS: 8.8.8.8

Secondary DNS: 8.8.4.4

then check again.
