The Internet Information Services (IIS) is an extensible web server software from Microsoft for use with Windows NT family. IIS supports HTTP, HTTP/2, HTTPS, FTP, FTPS, SMTP and NNTP. An application pool is a group of one or more URLs served by a worker process or set of worker processes. Application pools help to separate sets of IIS worker processes that share the same configuration and application boundaries. Here are some related IIS guides: How to add and remove IIS Web Server on Windows Server 2019 via the Server Manager and PowerShell, how to perform redirection from HTTP to HTTPS, and how to create a self-signed certificate using PowerShell.
Solution: These two steps out of all steps listed below solved my issue.

1. Assign the right in the Local security group too and

– Recreate application pools, websites, and shared configuration (if used)
– Make sure to use the same encryption provider (IISWASOnlyCngProvider or IISCngProvider) in applicationHost.config
