# Actions Connection Check
## What is this check for?
Make sure the runner has access to actions service for GitHub.com or GitHub Enterprise Server
- For GitHub.com
- The runner needs to access https://api.github.com for downloading actions.
- The runner needs to access https://vstoken.actions.githubusercontent.com/_apis/.../ for requesting an access token.
- The runner needs to access https://pipelines.actions.githubusercontent.com/_apis/.../ for receiving workflow jobs.
- For GitHub Enterprise Server
- The runner needs to access https://myGHES.com/api/v3 for downloading actions.
- The runner needs to access https://myGHES.com/_services/vstoken/_apis/.../ for requesting an access token.
- The runner needs to access https://myGHES.com/_services/pipelines/_apis/.../ for receiving workflow jobs.
## What is checked?
- DNS lookup for api.github.com or myGHES.com using dotnet
- Ping api.github.com or myGHES.com using dotnet
- Make HTTP GET to https://api.github.com or https://myGHES.com/api/v3 using dotnet, check response headers contains `X-GitHub-Request-Id`
---
- DNS lookup for vstoken.actions.githubusercontent.com using dotnet
- Ping vstoken.actions.githubusercontent.com using dotnet
- Make HTTP GET to https://vstoken.actions.githubusercontent.com/_apis/health or https://myGHES.com/_services/vstoken/_apis/health using dotnet, check response headers contains `x-vss-e2eid`
---
- DNS lookup for pipelines.actions.githubusercontent.com using dotnet
- Ping pipelines.actions.githubusercontent.com using dotnet
- Make HTTP GET to https://pipelines.actions.githubusercontent.com/_apis/health or https://myGHES.com/_services/pipelines/_apis/health using dotnet, check response headers contains `x-vss-e2eid`
## How to fix the issue?
### 1. Check the common network issue
> Please check the [network doc](./network.md)
### 2. SSL certificate related issue
If you are seeing `System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.` in the log, it means the runner can't connect to Actions service due to SSL handshake failure.
> Please check the [SSL cert doc](./sslcert.md)
## Still not working?
Contact GitHub customer service or log an issue at https://github.com/actions/runner if you think it's a runner issue.
