Behance SSL Certificate: net::ERR_CERT_AUTHORITY_INVALID

For the last several weeks, I've been unable to view Behance.net because Chrome flags it as having an invalid SSL certificate. I get the error code net::ERR_CERT_AUTHORITY_INVALID. Since my work doesn't allow me to bypass the warning, I can't visit Behance anymore.

I've tried deleting my temporary internet files for Behance and turning off extensions, ensuring my Chrome is up to date, attempting to visit from an incognito window, etc., but nothing seems to work. Has anyone else experienced this issue lately?
