Minecraft Server Joining/Loading Glitch (Failed to login:null)

poggers guy · Aug 5, 2021

I honestly don't know what I did wrong, (it works with ALL the clients i use, lunar or the OG vanilla client) it always says 'Failed to login:null' when I try to join a server (ex, Hypixel) even when I try to join an offline server.

I just migrated my Mojang account today and I was so exited to test out a skin that matches with the migrator cape in-game.. then it did this.

**My issue is only on Java, I have never played on any other version other than Java (Except when I get on some other device that is on mobile versions) and this is very saddening to me because I finally logged into my newly-migrated account and I run into this issue, if anyone can help I would appreciate it greatly!!**

**Xbox Category was selected because Microsoft/Xbox bought out Mojang, and there isn't a specific game category so yeah..**

Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

MatrixYeeted, by your report your pc is just not getting a connection, not being an account configuration error.

Tell me what appears in this test please. Download the companion xbox console app > settings > network > NAT type

And connectivity

Let's try this IP and cache cleanup, please

Type CMD in the search bar;

Right-click on the Command Prompt option;

Click on the Run as Administrator option;

From the Command Prompt screen, execute the commands described below, pressing Enter at the end of each line:

ipconfig /release <Enter>

ipconfig /renew <Enter>

ipconfig /flushdns <Enter>

ipconfig /registerdns <Enter>

nbtstat -rr <Enter>

netsh int ip reset all <Enter>

netsh winsock reset <Enter>

These commands are for resetting IP configuration and network-related caches that may be stored on your computer.

1.On the desktop, press the Windows + R keys simultaneously to open Run;

2. At run type cleanmgr and click OK to open Disk Cleanup;

3. In the Disk Cleanup window, select the C: drive (if asked) and click OK;

4. In the Disk Cleanup for Windows 10 window, select the checkboxes for the files shown and click Cleanup System Files.

5. After cleaning, check the checkboxes that are not checked again and click OK>Delete Files.

Do you have antivirus, vpn or firewall?

If so, disable them and see if the error persists.

I remain at your disposal if you have any further questions.
