Example URL:
*.my.salesforce.com

Steps to reproduce the problem:
1. Go to a particular instance of Salesforce as above.
2. Error message is shown about invalid cert auth & HSTS.
3. 

What is the expected behavior?
On non-Canary, I am able to log into the site without issue.

What went wrong?
The error message seems to pertain to an invalid cert auth, but the cert shows as valid. (It IS a Symantec cert though, so who knows.) Either way, either the cert is invalid, & it shouldn't show as valid, or it should be valid & I shouldn't get the error. The rest of the message about HSTS doesn't seem to make sense because I only ever try to access it via HTTPS.

Did this work before? Yes Whichever was the version prior to this that was released.

Chrome version: 66.0.3339.0  Channel: canary
OS Version: OS X 10.13.3
Flash Version: 

It works fine in other browsers, including non-Canary Chrome.
