Starting today, all 28 of our Azure DevOps hosted .Net builds are failing on the nuget restore task.
- task: DotNetCoreCLI@2 displayName: Restore inputs: command: restore projects: | $(BuildParameters.RestoreBuildProjects) $(BuildParameters.TestProjects) selectOrConfig: config nugetConfigPath: nuget.config
We have poked and prodded everything we can think of, but there's always just an extremely unhelpful message: error MSB4181: The "RestoreTask" task returned false but did not log an error.
-Enabling System Diagnostics (no better err msgs) -Changed to on-prem build agent(that worked but we can't leave it that way)
