 The runner is the application that runs a job from a GitHub Actions workflow. It is used by GitHub Actions in the [hosted virtual environments](https://github.com/actions/virtual-environments), or you can [self-host the runner](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners) in your own environment.

-## Common Network Related Issues
-
-### Common things that can cause the runner to not working properly
-
-- Bug in the runner or the dotnet framework that causes actions runner can't make Http request in a certain network environment.
-
-- Proxy/Firewall block certain HTTP method, like it block all POST and PUT calls which the runner will use to upload logs.
-
-- Proxy/Firewall only allows requests with certain user-agent to pass through and the actions runner user-agent is not in the allow list.
-
-- Proxy try to decrypt and exam HTTPS traffic for security purpose but cause the actions-runner to fail to finish SSL handshake due to the lack of trusting proxy's CA.
-
-- Proxy try to modify the HTTPS request (like add or change some http headers) and causes the request become incompatible with the Actions Service (ASP.NetCore), Ex: [Nginx](https://github.com/dotnet/aspnetcore/issues/17081)
-
-- Firewall rules that block action runner from accessing certain hosts, ex: `*.github.com`, `*.actions.githubusercontent.com`, etc.
-
-
-### Identify and solve these problems
-
-The key is to figure out where is the problem, the network environment, or the actions runner?
-
-Use a 3rd party tool to make the same requests as the runner did would be a good start point.
-
-- Use `nslookup` to check DNS
-- Use `ping` to check Ping
-- Use `traceroute`, `tracepath`, or `tracert` to check the network route between the runner and the Actions service 
-- Use `curl -v` to check the network stack, good for verifying default certificate/proxy settings.
-- Use `Invoke-WebRequest` from `pwsh` (`PowerShell Core`) to check the dotnet network stack, good for verifying bugs in the dotnet framework.
-
-If the 3rd party tool is also experiencing the same error as the runner does, then you might want to contact your network administrator for help.

-Otherwise, contact GitHub customer support or log an issue at https://github.com/actions/runner

-## SSL Certificate Related Issues
-
-You might run into an SSL certificate error when your GitHub Enterprise Server is using a self-signed SSL server certificate or a web proxy within your network is decrypting HTTPS traffic for a security audit.
-
-As long as your certificate is generated properly, most of the issues should be fixed after your trust the certificate properly on the runner machine.
-
-> Different OS might have extra requirements on SSL certificate,
-> Ex: macOS requires `ExtendedKeyUsage` https://support.apple.com/en-us/HT210176
-
-### Don't skip SSL cert validation
-
-> !!! DO NOT SKIP SSL CERT VALIDATION !!!  
-> !!! IT IS A BAD SECURITY PRACTICE !!!  
-
-### Download SSL certificate chain 
-
-Depends on how your SSL server certificate gets configured, you might need to download the whole certificate chain from a machine that has trusted the SSL certificate's CA.
-
-- Approach 1: Download certificate chain using a browser (Chrome, Firefox, IT), you can google for more example, [here is what I found](https://medium.com/@menakajain/export-download-ssl-certificate-from-server-site-url-bcfc41ea46a2)
-
-- Approach 2: Download certificate chain using OpenSSL, you can google for more example, [here is what I found](https://superuser.com/a/176721)
-
-- Approach 3: Ask your network administrator or the owner of the CA certificate to send you a copy of it
-
-### Trust CA certificate for the Runner
-
-The actions runner is a dotnet core application which will follow how dotnet load SSL CA certificates on each OS.
-
-You can get full details documentation at [here](https://docs.microsoft.com/en-us/dotnet/standard/security/cross-platform-cryptography#x509store)
-
-In short: 
-- Windows: Load from Windows certificate store.
-- Linux: Load from OpenSSL CA cert bundle.
-- macOS: Load from macOS KeyChain.
-
-To let the runner trusts your CA certificate, you will need to:
-1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
-2. Use `OpenSSL` to convert `.pem` file to a proper format for different OS, here is some [doc with sample commands](https://www.sslshopper.com/ssl-converter.html)
-3. Trust CA on different OS:
-    - Windows: https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate
-    - macOS: ![trust ca cert](./../res/macOStrustCA.gif)
-    - Linux: Refer to the distribution documentation
-      1. RedHat: https://www.redhat.com/sysadmin/ca-certificates-cli
-      2. Ubuntu: http://manpages.ubuntu.com/manpages/focal/man8/update-ca-certificates.8.html
-      3. Google search: "trust ca certificate on [linux distribution]"
-      4. If all approaches failed, set environment variable `SSL_CERT_FILE` to the CA bundle `.pem` file we get. 
-    > To verity cert gets installed properly on Linux, you can try use `curl -v https://sitewithsslissue.com` and `pwsh -Command \"Invoke-WebRequest -Uri https://sitewithsslissue.com\"`
-
-### Trust CA certificate for Git CLI
-
-Git uses various CA bundle file depends on your operation system.
-- Git packaged the CA bundle file within the Git installation on Windows 
-- Git use OpenSSL certificate CA bundle file on Linux and macOS
-
-You can check where Git check CA file by running:
-```bash
-export GIT_CURL_VERBOSE=1
-git ls-remote https://github.com/actions/runner HEAD
-```
-
-You should see something like:
-```
-* Couldn't find host github.com in the .netrc file; using defaults
-*   Trying 140.82.114.4...
-* TCP_NODELAY set
-* Connected to github.com (140.82.114.4) port 443 (#0)
-* ALPN, offering h2
-* ALPN, offering http/1.1
-* successfully set certificate verify locations:
-*   CAfile: /etc/ssl/cert.pem
-  CApath: none
-* SSL connection using TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256
-```
-This tells me `/etc/ssl/cert.pem` is where it read trusted CA certificates.
-
-To let Git trusts your CA certificate, you will need to:
-1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
-2. Set `http.sslCAInfo` Git config or `GIT_SSL_CAINFO` environment variable to the full path of the `.pem` file [Git Doc](https://git-scm.com/docs/git-config#Documentation/git-config.txt-httpsslCAInfo)
-> I would recommend using `http.sslCAInfo` since it can be scope to certain hosts that need the extra trusted CA.  
-> Ex: `git config --global http.https://myghes.com/.sslCAInfo /extra/ca/cert.pem`  
-> This will make Git use the `/extra/ca/cert.pem` only when communicates with `https://myghes.com` and keep using the default CA bundle with others.

-### Trust CA certificate for Node.js
-
-Node.js has compiled a snapshot of the Mozilla CA store that is fixed at each version of Node.js' release time.
-
-To let Node.js trusts your CA certificate, you will need to:
