 ## How to fix the issue?
 
-### 1. Check the common network issue
+### 1. Check global and system git config
+
+If you are having issues connecting to the server, check your global and system git config for any unexpected authentication headers. You might be seeing an error like:
+
+```
+fatal: unable to access 'https://github.com/actions/checkout/': The requested URL returned error: 400
+```
+
+The following commands can be used to check for unexpected authentication headers:
+
+```
+$ git config --global --list | grep extraheader
+http.extraheader=AUTHORIZATION: unexpected_auth_header
+
+$ git config --system --list | grep extraheader
+```
+
+The following command can be used to remove the above value: `git config --global --unset http.extraheader`
+
+### 2. Check the common network issue
   
   > Please check the [network doc](./network.md)
 
-### 2. SSL certificate related issue
+### 3. SSL certificate related issue
 
   If you are seeing `SSL Certificate problem:` in the log, it means the `git` can't connect to the GitHub server due to SSL handshake failure.

-## Features
-- Allow self-hosted runner admins to fail jobs that don't have a job container (#1895)
-- Experimental: Self-hosted runner admins can now use scripts to customize the container invocation in the runner (#1853)
 ## Bugs
-- Fixed an issue where a Job Hook would fail to execute if the shell path contains a space on Windows (#1826)
-
+- Fixed an issue where job and service container envs were corrupted (#2091)
 ## Misc
-- Handle new `HostedRunnerShutdownMessage` to shutdown hosted runners faster (#1922)
 
 ## Windows x64
 We recommend configuring the runner in a root folder of the Windows drive (e.g. "C:\actions-runner"). This will help avoid issues related to service identity folder permissions and long file path restrictions on Windows.
