sitecore site in unreachable

When you install the Sitecore site locally and get the following error something like shown in SS below, after successful installation, obviously your site will not be support.cloudflare.com but will be something like https://yoursitesc.dev.local/

This means that the issue is because of the certificate. So, you will need to install the self signed certificate which should not take more than 2 minutes. Follow the article https://sitecorepeanuts.blogspot.com/2024/06/sitecore-self-signed-certificate.html to create a self signed certificate for your

1. Sitecore site

2. Identity site

3. xConnect site

Then again try after restarting the IIS.

Thanks!
