Question

Hi All,

I am getting the error "Unable to load the service index for source https://api.nuget.org/v3/index.json while restoring Nuget packages in VS 2022. I have tried to delete Nuget config file as well but it did not help. Can anyone please provide assistance?

Answer 1

Hi @Munjal, Kanha (Gurugram) ,

You can try clearing the NuGet cache using the command nuget locals all -clear.

Or try updating your vs2022 to the latest version.

If you're behind a proxy, ensure your proxy settings are correctly configured.

• Open Visual Studio.
• Go to Tools > Options > Network.
• Configure your proxy settings accordingly.

Also check nuget.config reference about proxy.

Best Regards.
