Proxy interfering with Azure Server/ NuGet Push Error404

Question

I tried to Push a nupkg to Artifacts in Azure DevOps Server, but it fails with the following error:

---> (Inner Exception #0) NuGet.Protocol.Core.Types.FatalProtocolException: Unable to load the service index for source http://<DomainName>/nuget/v3/index.json ---> System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).

I suspect that the problem might be the corporate's proxy that interferes with Azure DevOps Server.

Proxy's configuration looks like this:

 <?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
  </packageSources>
  <config>
        <add key="http_proxy" value="http://ep.threatpulse.net:80" />
  </config>
</configuration>

Also, I tried to configure the proxy settings and it still didn't work.

Does anybody have any idea about what could be wrong or how can I fix this?

Version Dev17.M153.5

Yes, that error is indeed caused by proxy and what you did is also correct.

Just make sure you have add proxy settings into Nuget.Config file, which located in following path:

%appdata%\NuGet\NuGet.config

NuGet.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <config>
        <add key="http_proxy" value="http://ep.threatpulse.net:80" />
        <add key="https_proxy" value="http://ep.threatpulse.net:80" />
    </config>

  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
  </packageSources>

</configuration>

You could check this thread for some more details.

If it still not work for you, I suggest you contact your office IT to confirm proxy setting.

Hope this helps.
