NET::ERR_CERT_COMMON_NAME_INVALID

gin-profile.thedev.id normally uses encryption to protect your information. When Chrome tried to connect to gin-profile.thedev.id this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be gin-profile.thedev.id or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

You cannot visit gin-profile.thedev.id right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

@fransallen I still don't understand, can you help?

Have you set the custom domain on your GitHub page (or host)?
