I am facing similar error in my local machine after setting up the certificates and project on VDP

Hi @Suvin, 

The error you're seeing is due to basic authentication not being sent in the header with username and password base64 encoded.

Please refer to the Two-Way SSL guide linked above.

Thanks,
