Unable to load service index for source while restoring NuGet package

Question

I'm trying to restore a .NET NuGet package using the restore command, and I'm getting this error

Unable to load the service index for source https://nuget.telerik.com/v3/index.json.

I already have an external feed with the credentials, as well as a nuget.config file. Here's my YAML code

steps:
- task: UseDotNet@2
  inputs:
    version: '7.x'
    includePreviewVersions: true 

- task: NuGetAuthenticate@1
  inputs:
    nuGetServiceConnections: 'TelerikFeed'
    forceReinstallCredentialProvider: true

- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: '**/*.sln'
    feedsToUse: 'config'
    nugetConfigPath: './MBWorks/nuget.config'
    externalFeedCredentials: TelerikFeed
  timeoutInMinutes: 10

Hi @Khaled Khalifa

To troubleshoot connectivity issues with; what I'm assuming, Azure DevOps is best to ask the DevOps community or tech community. That particular audience doesn't regularly monitor questions on Q&A.

What I would do is confirm there's no issue with the task. Try setting up your own NuGet source like myget.org and see if restore command still fails. If it does, then it seems like an issue with the task. If it doesn't then it's likely a network connectivity issue between host running the pipeline and the Telerik NuGet source.
