Error with QB Enterprise 2016 and Web Connector setup

Installing the web connector inside QB Enterprise 2016, and I keep getting an error qbwc1048 about verifying the certificate. I am wondering if there is a known issue or has Intuit added new requirements to the QWC file for security? I found some indication that might be the issue, so I created a copy of the file with the <CertURL> tag but still got the same error 1048. Anyone else see this problem? Thanks!
