Your connection is not private NET::ERR_CERT_COMMON_NAME_INVALID

Finally banging head on desk for two days I found this setting in chrome://flags/ to Allow invalid certificates for resources loaded from localhost. finally no disable all certificate error, only for localhost. Adding answer for someone struggling with same issue.

We have found that the best (and only) way to override Chrome is to type the phrase thisisunsafe at the Chrome generate webpage that blocks you. We have servers on an internal network which use SSL but which are not externally signed and this is the only way to get to them.
