Failed To Login the Authentication Servers are Currently Not Reachable Minecraft

The error message “Failed to login: The authentication servers are currently not reachable” usually means your computer is blocking Minecraft from connecting to the internet, rather than the servers actually being down.

This is extremely common if you have ever used “Alt Account” generators (like TheAltening, MCLeaks) or if your network settings are stuck.

Here is the step-by-step fix, ranked from most likely to least likely.

1. The “Hosts File” Fix (Most Common Cause)

If you have ever used software to get free Minecraft accounts (Alt dispensers), they modify a hidden file on your computer to block the real Mojang servers. You must fix this to play.

For Windows:

1. Click Start, type Notepad.

2. Right-click Notepad and select Run as Administrator (Crucial).

3. In Notepad, go to File > Open.

4. Navigate to this folder: C:\Windows\System32\drivers\etc

5. Change the file type drop-down (bottom right) from “Text Documents” to “All Files”.

6. Double-click the file named hosts.

7. Look for any lines that contain mojang.com or minecraft.net.

8. Delete those lines completely.

9. Save the file (Ctrl + S) and restart your computer.

For Mac:

1. Open Terminal.

2. Type sudo nano /etc/hosts and press Enter (type your password when prompted).

3. Delete any lines containing mojang or minecraft.

4. Press Ctrl + O to save and Ctrl + X to exit.

2. Flush Your DNS

Your internet “phonebook” might be outdated. This forces a refresh.

1. Press the Windows Key and type cmd.

2. Open Command Prompt.

3. Type this command and press Enter:

   Bash

   ipconfig /flushdns
   

4. Then type this command to reset the connection:

   Bash

   netsh winsock reset
   

5. Restart your computer.

3. Force IPv4 (For Java Edition Users)

Sometimes Java tries to use IPv6 (a newer internet protocol) and fails. You can force it to use the older, more stable IPv4.

1. Open the Minecraft Launcher.

2. Go to Settings (bottom left).

3. Ensure “Java Edition” is selected.

4. Look for “Java Arguments” (you may need to check a box that says “Advanced”).

5. Scroll to the end of the line of text in the box.

6. Add a space, and then paste this exact text:

   Plaintext

   -Djava.net.preferIPv4Stack=true
   

7. Click Save and launch the game.

4. Log Out and Back In

Your “Access Token” might have expired.

1. In the Minecraft Launcher, click your profile name in the top left.

2. Click Log Out.

3. Log back in with your Microsoft Account.

5. Check if Servers are Actually Down

It is rare for only the auth servers to be down while everything else works, but it happens.

• Check DownDetector for Minecraft.

• If you see a massive spike in reports (in the thousands), the issue is on their end and you just have to wait.
