In our Outbound Messaging Delivery Status we are receiving an error message "javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated"

But, we have a valid cert as distinguished here:
https://www.sslshopper.com/ssl-checker.html#hostname=admin.clearcareonline.com
This shows that we have a valid cert chain.
https://developer.salesforce.com/page/Outbound_Messaging_SSL_CA_Certificates
starfieldclass2ca is listed and is in the chain
openssl s_client -connect admin.clearcareonline.com:443 |egrep -i starfield
s:/C=US/O=Starfield Technologies, Inc./OU=Starfield Class 2 Certification Authority

And, both the certs on Salesforce and our Site have a matching SHA1.

What needs to happen to ensure that Salesforce accepts our cert?

Hi,

I am looking for some help with the following:

I get the following error when attempt to send outbound message to my test server: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

- I have a real certificate installed on the server.
- I am also able to view the listener description when I point browser on my dev workstation to the test server (same URL as the endpoint specified in my O/B message).
- In the IIS log, I can see all the hits from my dev workstation, but no hits from either of SFDC IPaddresses (204.14....)

Appreciate any info that will help me understand and debug this, or at least point me in the right direction.

Thanks!
