I ran into this issue, but the above method did not work for me as I ran into errors from openssl on generating the certificate. It didn't like something in the request file. So I accomplished the above using the command below which takes you through a set of interactive prompts:
sudo openssl req -x509 -nodes -days 730 -newkey rsa:3072 -keyout /etc/ssl/private/server.key -out /etc/ssl/certs/certificate.pem
I then ran through the rest of the commands above to replace the default certificate with a self-signed certificate that was generated. And then I opened Google Chrome to go to the webpage for Expedition and alas, it DIDN'T work! I got the same error as before:
NET::ERR_CERT_INVALID website sent scrambled credentials Self-signed Certificate
And no option to proceed. Well, this was frustrating, especially after checking this on Firefox and seeing that it works. After googling this around, I came up on a solution that I hope would help others here. When you hit the webpage for Expedition using Google Chrome and come across this error without an option to proceed, just type:
badidea
or:
thisisunsafe
And voila! The webpage will come right up. Hope this helps!
