A report from reddit:

https://pay.reddit.com/r/chrome/comments/5ylr3s/chrome_dev_58030296_takes_ssl_certificates_common/

"
I am using HTTPS on my home network. I tried to connect to the website from my laptop, but Chrome kept saying ERR_CERT_COMMON_NAME_INVALID. I checked the certificate, and the certificate itself was all right. The only thing I suspect is that the name is starting with a capital letter like "Doge". So, when I tried to access the page by an address "https://doge/such.page", I think Chrome treated "doge" != "Doge" and thus, a wrong certificate.

I do not think domain names are case-sensitive. So, if this is the case, I think it is a bug.

I do not know why the dev version of Chrome had been installed on my laptop in the first place. Probably, it was a mistake. I uninstalled it and installed the stable version, and the problem is gone.
