IIS wordpress rewrite issue

Hello;

I have IIS on Windows server 2016 running PHP and MySQL and i have wordpress website installed to intpub folder.

My problem is when accessing the website example.com it's give me "The page isn’t redirecting properly" but when i access it with example.com/index.php it's working just fine.

Why without index.php not working and with index.php specified on link working fine.

Also i have this rewrite rules to enable the Wordpress Permalinks.

==

<rewrite>
<rules>
<rule name="Main Rule" stopProcessing="true">
<match url=".*" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
