Fix: Minecraft Failed To Authenticate Your Connection

You may have failed to authenticate your connection while connecting to a Minecraft server.

This problem can arise because of an unstable network connection or if the specific server the user is connected to is down or has other issues.

If you are encountering this annoying problem, then I will show you how to fix it.

So, follow this article.

What To Do When Minecraft Failed To Authenticate Your Connection?

If Minecraft failed to authenticate your connection, then follow the methods mentioned below to easily reestablish the connection.

Fix 1: Restart Your Game Launcher

If Minecraft launcher could not connect to server properly, the first thing you can try is to restart the launcher.

Follow the steps given below to do so:

  • Right-click on your Taskbar and select Task Manager.

Open_task_manager_from_taskbar_menu

  • In the Processes tab, locate Minecraft and right-click on it.

end_task_minecraft

  • Select the End Task option to terminate the process. Allow some time and then restart the game launcher.

Now start Minecraft and see if you can connect it to the server. If the issue persists, try the next solution.

Fix 2: Power Cycle Your Router

Turn off your system and disconnect the internet router from the power socket.

Look for the power button on the router. Press and hold the button for 15-30 seconds.

Plugin the router back to the power socket and then press the power button again to switch it on.

Wait till you get internet access and check if you are able to connect to the Minecraft server now.

Fix 3: Use Direct Connect Feature

The multiplayer has a direct connect feature and with the help of this feature, one can connect to the server directly.

So, if the server failed to authenticate your connection on Minecraft, try this process to establish connection:

  • Go to the Multiplayer Launcher and open the server list.
  • You will see the direct connect option at the bottom. Click on it.

  • Type the server name and press the connect option.

Allow few moments and check if the game can connect to the server now.

Fix 4: Reconnect To Hypixel Server

A high number of users have reported that they are facing this issue while trying to connect to the Hypixel server.

If there is any glitch in the Hypixel server, then Minecraft will not be able to authenticate the connection.

Here I suggest you rejoin the server. But, before you do this, quit Minecraft and end any background processes.  

Follow the steps mentioned below to do it:

  • Close Minecraft and then follow the Fix 2 to end the background processes from Task Manager. Now, open the Launcher and click on the Singleplayer option.

minecraft_single_player

  • Continue with the game for a few minutes and then exit. Now open the launcher again and select Multiplayer this time. Click on the Add Server.

Add_server_on_minecraft

  • After that, type mc.hypixel.net in the provided box to add the hypixel server.
  • If Minecraft launcher could not connect to the server, then open the server box again and try adding or joining the following servers:
hypixel.net

stuck.hypixel.net

If you have established the connection now, then again enter mc.hypixel.net in the box.

Check if the connection authenticates now. If not, then move on to our next solution.

Fix 5: Allow Minecraft Traffic Through Windows Defender Firewall

Windows Firewall can stop Minecraft from connecting to such servers. Tweaking the rules for Minecraft in Windows Defender Firewall can fix this issue.

To do it, first make sure all the Minecraft processes are closed (follow Fix 2).

Now follow the steps as described:

  • Go to the Start Menu and enter Windows Defender Firewall Advanced Security in the box and choose the first option.

windows_defender_firewall_with_advanced_settings

  • From the top left panel click on Inbound Rules.

inbound_rules_in_windows_defender_firewall_with_advanced_settings

  • Now locate Minecraft and double click on it. This will open the Properties window.
  • Select the Allow the connection option in the Action section. Click on Apply and OK.

allow_connection_in_minecraft_inbound_rule

  • Now click on New Rule from the right-side panel. Select Program on the first window and click on Next.

New_rule_type_program_in_windows_defender_Firewall

  • Click on the Browse option and navigate to Minecraft’s installation folder. If you don’t know the path, right-click on the Minecraft shortcut on your desktop and select Open File Location option.
  • In the Minecraft installation folder, look for the JRE-x64 folder. Open the Bin folder next.
  • Find javaw.exe in the Bin folder and hit the Open button. Select Next to move to the next window.
  • Click on the Allow the Connection option on the Action window and select Next.

allow_connection_New_rule_in_windows_defender_Firewall

  • Check Private, Domain and Public boxes in the Profile folder.

check_all_profiles_in_New_rule_in_windows_defender_Firewall

  • Name the rule to finish the process. Now repeat these steps for the Java.exe file in the same Bin folder.
  • Create the same rules in the Outbound Rules This will hopefully solve your problem.

If the problem is not solved this way, then try the following.

  • Go to the Action tab and click on new rule.

new_rule_from_action_tab_in_windows_defender_firewall_advanced_settings

  • From here select the Port option and click on Next.
  • Check the Specific local ports option and input 25565 in the given box. Click on Next.

set_rule_for_port_in_windows_defender_firewall_advanced_settings

  • Select the Allow the connection option in the Action window. Click on Next.
  • Check all the Profiles and select Next. Name the rule and finish the process.

Minecraft should now connect to the server without any issue.

Fix 6: Edit The Host File

Host files are OS files that maps the hostnames to the IP addresses. The Minecraft servers can be blocked by your Host file if it was edited by someone.

Check if the Host file is blocking the server. Here is how you can do it:

  • Go to the Windows search box and type Notepad.
  • Now Right-click on the notepad app and run it as administrator.

run_paint_as_administrator

  • After Notepad opens, click on the File tab and from the pop-up menu select Open.
  • Enter the following path in the File name section:
C:\Windows\System32\Drivers\etc\hosts

path_to_host_file_on_note_pad

  • Now, press Ctrl + F to open the Find menu.
  • Here enter “Mojang” and check if it finds anything in the host file. If it does, delete those entries.

find_entries_with_mojang

  • Check for Minecraft next and also delete those entries.
  • Save your changes and then see if Minecraft can connect to the server now.

Closing up

Hope you will no longer fail to authenticate your connection to the Minecraft server after performing the above steps.
