Webserver error on connection NET::ERR_CERT_INVALID

Postby pastro50 » Thu Sep 03, 2020 8:10 am

When I connect to the raspberry PI webserver with the ad2pi board, I get this message on Chrome: NET::ERR_CERT_INVALID.
Latest Chrome won't let me connect with this error. Any idea how to fix this?
Thanks

I ended up deleting the certificate on my MAC and connecting with Safari which complained but created a new certificate. After that it appears that it works ok on Chrome. Also could type thisisunsafe on the chrome page and it would let me in.

The SSL is secure its just a private key that only you have on your Pi. It is generated at first boot.

That being said browsers dont understand this and just know it does not have a 3rd party certificate.

"If not, you can try typing “badidea” or “thisisunsafe” directly in chrome on the same page. Don’t do this unless the site is one you trust or develop. The text “badidea” and “thisisunsafe” says a lot!"

The trouble was that Chrome didn't allow me to bypass (like it used to) and go to the site. Like you mentioned though - blindly typing thisisunsafe into the webpage allowed it to work. It's all sorted now. Thanks for your help.
