I have a client who uses our Shopify app. The app is distributed from our domain. The issue is when a client visits his store, the app doesn’t work on the storefront, and there is an error in the browser console: net::ERR_CERT_COMMON_NAME_INVALID
This issue appears only when he uses Windows with any browser. But when he uses macOS or a smartphone - there is no error and the app works properly. Also, there is no problem when he uses a smartphone with mobile internet. He cleaned all browser data and cash - but didn’t help.
Our domain has a valid SSL certificate, and Total TLS enabled with Google Trust Service.
What is the problem can be?
