Anyone else having trouble with Chrome v55 and web filtering set to authenticate?

Haven't updated my firmware in a while, we're on 5.2.1.  We have social networking set to require authentication, so teachers can use it, but students can't.  Worked great until machines started updating to v55, now we get a "your connection is not private" error.  Chrome complains the cert uses SHA-1, and also gives net::ERR_CERT_COMMON_NAME_INVALID.   Is anyone else seeing it, and have you been able to resolve it?  Is this something an upgrade to the firmware will fix?

We are also having the same issue. Works fine in IE though.
