How to redirect a URL in IIS to fully qualified domain name and https

I'm trying to use the URL Rewrite module in IIS to redirect the four urls below. All but one are working but I can't figure out what is wrong.

1.) http://site1.company.com/web1  ->>   user is redirected correctly to:     https://site1.company.com/web1
2.) http://site1/web1  ->> user is redirected correctly to:    https://site1.company.com/web1
3.) https://site1.company.com/web1  ->> user goes to this site, no redirect needed
4.) https://site1/web1   ->>  This should redirect to https://site1.company.com/web1 but it does not work.  In the browser we get the ssl error that connection not valid.

Number 4 is not working. The same rule that sets the url in #2 should also do the job in #4. What am I missing?

Here are my two rules. I first add .company.com if it's not there and then add https if needed.

---- Here i the rule to add the FQDN:

<rule name="Redirect site1 to FQDN" enabled="true" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{HTTP_HOST}" pattern="^site1\.company\.com$" negate="true" />
                    </conditions>
                    <action type="Redirect" url="http://{HTTP_HOST}.company.com/{R:1}" redirectType="Permanent" />
                </rule>

----Here is the rule to change http to https:
                <rule name="Redirect Http to Https" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{HTTPS}" pattern="^OFF$" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" />
                </rule>
