Hi @sarthakgupta-0705
First thing, you can change your DNS to Google DNS in Network Connection.
In addition, you can check:

  • Date and time in your computer

  • Proxy settings for internet connection

  • Any restriction from antivirus?

Hope it works.
Thank you

Hello @sarthakgupta-0705,

This is related to a certificate issue in your local computer.

You can fix this by adding your root CA cert with certutil

You may refer some examples here to carryout the certificate import : https://stackoverflow.com/questions/23869177/import-certificate-to-trusted-root-but-not-to-personal-command-line

Hi sarthakgupta-0705!

I also agree with ManuPhilip idea. The error is related to certificate issue.

It recommends you try to add your root CA with certutil:

As a supplement, you can refer to:
