Hi Mohammed, Mohd Faizal,

Thank you for reaching out to Microsoft Q & A forum.   

It looks like you’re encountering a permission issue when running Invoke-WebRequest over ssh.exec() on Windows 11. Since this works on Windows 10, the problem is likely due to Windows 11’s stricter security settings. 

1.Run PowerShell as Administrator and try again. 

2.Modify the execution policy by running: 

Set-ExecutionPolicy RemoteSigned -Scope Process -Force

3.Use Start-Process with elevated privileges: 

Start-Process powershell.exe -ArgumentList "-Command Invoke-WebRequest -Uri '$DOTNET_INSTALL_SCRIPT_URL' -OutFile '$working_dir\..\dotnet-install.ps1'" -Verb RunAs

 4.Check Windows Defender or antivirus settings, as they might be blocking the script. 

5.Verify Group Policy restrictions if this is a company-managed device, as they may limit remote script execution. 

If the issue persists, check Event Viewer logs or try manually downloading the script outside of SSH.
