Whitelist for Chrome “Your Connection is Not Private”

The best (and only) solution that I have found is to type the passphrase thisisunsafe as soon as you see the “Your Connection is Not Private” message. We have servers on an internal LAN where we regularly get blocked by Chrome. This passphrase is the only way to get to them.

In chrome://flags/ there's a new option named Allow invalid certificates for resources loaded from localhost. that you can enable.

chrome://flags/#allow-insecure-localhost

Have you tried to add --ignore-certificate-errors tag in Google Chrome shortcut to bypass SSL warning? According to this post, it's a method to bypass & ignore the SSL warning.
