net::ERR_CERT_AUTHORITY_INVALID

I have a project on NodeJs(backend) and Angular9(frontend). I was doing a SignUp.I have this api from the backend(NodeJs) side

             http://localhost:3001/account/login 

and upon implementation the project was running and it moved me from the SignUp page to other pages within the application and it was moving me from the login page to another page inside the application,But I changed the api, instead of http, I put https

         https: // localhost: 3001 / account / login

But the application no longer works. It just displays the SignUp page, and when I enter the data it does not transfer me to other pages.And I have this error that appeared when I Click "Inspect" in Chrome:

        POST https://localhost:3001/account/login         net::ERR_CERT_AUTHORITY_INVALID

How Can I Solve This Problem?
