IIS reverse proxy to nodejs app via https problem - node.js

Question

I am building a nodejs api that is hosted by iis. It works perfectly over (using port 5000) http. However, when trying to use the https connection if fails(ssl are installed). I either get a connection failed message or a refused message.
<handlers accessPolicy="Read, Execute, Script" />
<rewrite>
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="http://localhost:5000/{R:1}" />
<conditions>
<add input="{HTTPS}" pattern="off" />
</conditions>
</rule>
<rule name="ReverseProxyInboundRule2" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="http://api.mysite.com:5000/{R:1}" />
</rule>
</rules>
<outboundRules>
<preConditions>
<preCondition name="ResponseIsHtml1">
<add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
</preCondition>
</preConditions>
</outboundRules>
</rewrite>
Seems like IIS is refusing the connection. any help is appreciated.

Answer 1

According to your url rewrite rule, I found all your https request will match the ReverseProxyInboundRule2 and rewrite to "http://api.mysite.com:5000". I suggest you could firstly check you could access the "http://api.mysite.com:5000".
I guess there is something wrong with this url. It seems you doesn't bind the domain in the IIS binding configuration.
I suggest you could try to open the IIS web application binding to add the domain for the http://api.mysite.com.
