I found this in my Chrome console:
The SSL certificate used to load resources from https://bam.nr-data.net will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See Google Online Security Blog: Distrust of the Symantec PKI: Immediate action needed by site operators for more information.
What is loaded from bam.nr-data.net?
Hi Giri,
It’s an issue with one of our 3rd parties and it is already solved in a future release.
You can safely ignore this message 
Hi Tomer, can you provide an update on this issue? Seems like March 15 is your deadline to fix before our users start getting impacted?
According to Google,“Chrome 66 has already been released to the Canary and Dev channels, meaning affected sites are already impacting users of these Chrome channels. If affected sites do not replace their certificates by March 15, 2018 , Chrome Beta users will begin experiencing the failures as well.”
Hi, our systems team is on it. Note that we officially support the stable version of Chrome, which will be released around a month after the beta version.
