The SSL connection could not be established on Windows Runner for Github

Question

I have a Windows Server 2019 Data Center on which I am setting up github action runner. Windows Version - 1809

While executing the command -

./config.cmd --url https://github.com/org/repo --token myPAT

I am getting the error - The SSL connection could not be established, see inner exception.

I am seeing the same error while executing workflow which runs on runner which was already hosted on that machine. It was working but suddenly started getting this error.

Full logs --
