CFHTTP with https not working after server IP change (CF 10, Windows Server 2008 R2)

Hi,

We noticed that a call to https://www.googleapis.com/ via CFHTTP stopped working after our sysadmin switched the IP of our web server.

The error from ColdFusion is:

JSON parsing failure at character 1:'C' in Connection Failure

After researching, I tried using the keytool ([CF 10 root]/jre/bin/keytool.exe to import the top-level certificate (GeoTrust Global CA), which was exported from Google Chrome 42 in DER format.

I used the following flags:

-import -v -alias GAGLOBAL -file [.cer location] -keystore cacerts -storepass [password]

It appeared to add correctly, as it displayed the owner, issuer, etc. and asked if I wanted to trust the certificate. I replied "yes", and it responded "Certificate added to keystore" [Storing cacerts]. I then restarted the CF 10 application service. The same error persists.

Please advise.

Thanks,

Dave
