My website is secure in other browsers including chrome in the mobile version, but it is not secure in Chrome Laptop version

Hi, My website is secure in all the browsers except in Chrome. It even shows secure in chrome (mobile version), but not in laptop version.

Please guide me on how to resolve the issue.

Can you screenshot the URL bar, and/or click the padlock (or where the padlock should be)? That will tell us what the problem could be.
