OpenNMS HTTPS Monitor & IIS Rejecting connections

Hi all,

The latest version of IIS seems to be giving me some headache on monitoring using OpenNMS.

Our IIS runs three web services using server name indication. Each one is a TLS website on port 443.


Our webserver will respond with this:

https://joe.test.co.uk/login.asp
HTTP request sent, awaiting response... 200 OK
Length: 2591 (2.5K) [text/html]
Saving to: ‘login.asp’

but will not respond with this

https://192.168.201.30/login.asp

Connecting to 192.168.201.30:443... connected.
Unable to establish SSL connection.

curl -1 https://192.168.201.30/login.asp
curl: (35) TCP connection reset by peer

It seems that IIS rejects the connection when attempted to connect to via IP address. Does anyone have any what setting I need to change to permit it to connect via IP (And then use the SNI to check which server it actually services up)

The server I have setup is below – and it gets the java connection error message as below. I guess it falls into the same issue.


  <service name="CAB - TssPlansRegistry" interval="60000" user-defined="false" status="on">
         <parameter key="host-name" value=" joe.test.co.uk "/>
         <parameter key="retry" value="3"/>
         <parameter key="timeout" value="5000"/>
         <parameter key="port" value="443"/>
         <parameter key="url" value="/login.asp"/>
         <parameter key="response" value="200"/>
   </service>

Cheers for any help.
