Hi @yannou38, We are unable to reproduce the error you are experiencing. We've successfully installed the dotnet without encountering any errors.
Here are a few troubleshooting steps to help resolve the issue.

• Proxy Settings: Verify that your proxy settings are correctly configured and that the values provided are valid.
• Try Different Proxy: If possible, test with a different proxy server to rule out issues specific to the current proxy.
• Check Self-Hosted Runner Configuration: Ensure that the self-hosted runner is configured correctly and has the necessary permissions to set the proxy and run the script.
• Run Script Locally: Try running the install-dotnet.ps1 script locally to see if the issue persists outside of the GitHub Actions environment.

If the problem continues, please provide more details about your environment, setup and attach link to the build or public repository. So we can assist further.
