I am using azure devops on prem (previously called TFS). And I have a problem with build agent. When the agent is trying to download the latest microsoft .net core SDK it fails with self signed certificate in certificate chain error.
Here is the full error:

I had a look on agent code on github and I think problem is in this method:
I coudn't dig deeper in the projec itself but I think it is using this azure-pipelines-tool-lib/tool But I coudn't find anything that would help me there either.
Any suggestions or configurations to check?
My workaround so far is to download the sdk manually and place it into cache folder (agent_work_tool\dotnet\sdk) of the agent, but I would have to do that every time microsoft releases new major version.
