Hi. I have created a brand new site using Kentico Xperience v13 with the site as .NET Core 5.0. I have created separate sites in IIS for the CMS admin portal and the website, both have HTTPS bindings with self-signed certificates that are in the trusted certificates store on my local development machine. However, when I try to create the very first page (the homepage), I get the following error message in the admin portal:@An error occurred while attempting to retrieve page templates. Contact your system administrator and check that the page builder feature is registered correctly in the MVC project@And this error is logged to the event log:Message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
Exception type: System.Net.WebException
