Hi Samco, 

Thanks for the reply!!.  The certificate CA is the same and all the Cert Parameters is also the same.  But not sure why it did not work which we are investigating. 

I Understood , that telnet will not work due to https but do we need to specifically mention the certificate and key for the other two methods.??. Cos i am getting http 400 series error, which means SSL is passed right and i assume something else causing this.

Yes, the HTTP 400 and 403 response mean you managed to established the SSL/TLS connection. But it does not mean the certificate check is ok for the server, it could establish the connection then inspect the certificate (IIS can make this from my experience).

Anyhow, if your health monitor need the client certificate to work, it mean you need it to replicate it with curl.

good luck,

Cheers,

Sam
