There we go. google-chrome 74 refuses to connect to mhttpd configured with a self-signed certificate generated per instructions printed by mhttpd.

Here is the full error text (there is no button to "let me connect to it anyway"):

Your connection is not private
Attackers might be trying to steal your information from musr03.triumf.ca (for example, passwords, messages, or credit cards). Learn more

musr03.triumf.ca normally uses encryption to protect your information. When Google Chrome tried to connect to musr03.triumf.ca this time, the website sent back unusual and incorrect credentials. This may happen when an 
attacker is trying to pretend to be musr03.triumf.ca, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.

You cannot visit musr03.triumf.ca right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.
