Or Unknown host: peer not authenticated on Railo. Either way its a PITA when this happens.
On Lucee/Railo the fix was easy.
- Go to the server Admin.
- Click on SSL Certificates under "Services"
- Enter you host an port then click list
- Then click install.
For ColdFusion it was a little bit more involved.
- Go to the site you are having trouble with i.e. https://www.example.com and download the root certificate and save it as cert.cer (Google will tell you how)
- (optional I think)
[JAVA_HOME]keytool -delete -alias [CERT ALIAS YOU WANT TO REMOVE IF ALL READY INSTALLED]
[JAVA_HOME]keytool -import -alias www.example.com -keystore [YOUR PATH TO]cacerts -storepass [STOREPASS PASSWORD] -trustcacerts -file [YOUR PATH TO]cert.cer
n.b. on Adobe CF your JAVA_HOME is probably something like [COLDFUSION HOME DIRECTORY]\runtime\jre\bin
