Receiving `NET::ERR_CERT_AUTHORITY_INVALID` error with .app domain
I'm trying to make example.app work with my linode’s webserver but always receive the following error message:
Your connection is not private This server could not prove that it is *example*.app; its security certificate is not trusted by your computer's operating system. This may be caused by a misconfiguration or an attacker intercepting your connection. NET::ERR_CERT_AUTHORITY_INVALID
It sounds like you’re running into trouble thanks to HSTS (HTTPS Strict Transport Security). As a security measure, HSTS forces browsers to always use https (instead of http) for your website. Since Google added the entire .app domain to an HSTS Preload List, you will need an SSL certificate for any .app site to be viewable.
For more detail on HSTS check out the Wikipedia entry.
