web.config https redirect rule does not work

Hi

I have the following web.config

<?xml version="1.0" encoding="utf-8"?><configuration><system.webServer><staticContent><remove fileExtension=".json" /><mimeMap fileExtension=".json" mimeType="application/json" />	  <mimeMap fileExtension="woff" mimeType="application/font-woff" /><mimeMap fileExtension="woff2" mimeType="application/font-woff" /> </staticContent><!-- IIS URL Rewrite for Angular routes --><rewrite><rules><rule name="Angular Routes" stopProcessing="true"><match url=".*" /><conditions logicalGrouping="MatchAll"><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /><add input="{REQUEST_URI}" pattern="^/(api)" negate="true" /></conditions><action type="Rewrite" url="/" /></rule><rule name="Redirect to HTTPS" stopProcessing="true"><match url="(.*)" /><conditions><add input="{HTTPS}" pattern="^OFF$" /></conditions><action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" /></rule></rules></rewrite></system.webServer></configuration>

but redirecting to https does not work.

Anyone knows why?

Thanks in advance
