Hello Ayan A, My name is Khaji I am the independent advisor and I will be happy to help you today.

It's important to note that Minecraft Java Edition is not directly associated with Xbox profiles. Minecraft Java Edition is a separate version of Minecraft that is primarily for Windows, Mac, and Linux platforms.

Here are a few steps you can try to troubleshoot the login error:

1. Double-check that you are entering the correct username and password for your Minecraft Java Edition account. Ensure that there are no typos or errors in the login information.

2. Make sure you have a stable internet connection. A weak or intermittent connection can cause login issues. Restart your router or switch to a different network to see if that resolves the problem.

3. If you are unsure about your Minecraft account password or suspect it may be incorrect, you can try resetting your password. Visit the official Minecraft website and follow the instructions for password recovery.

4. Occasionally, Minecraft's login servers may experience temporary issues. You can visit the official Minecraft server status page or check Minecraft's official social media accounts for any announcements regarding server problems. If there is a known issue, you may need to wait until it is resolved.

5. If you've tried the above steps and are still unable to log in, it's recommended to reach out to Minecraft support for further assistance. They will have access to specific account information and can help troubleshoot the login error.

Thank you very much for your patience and understanding! If you need anything else, do not hesitate to contact us again.

No I can't it just says something with invalid login or session everytime i try to join a minecraft server.

I actually discovered a way to login.

Before opening the Minecraft app, switch for mobile data and login into your account.

After the login, turn the wi-fi back on, and you'll be able to play normally in servers.
