Did Not Connect: Potential Security Issue
Firefox detected an issue and did not continue to protokolle.zapf.in.
The website is either misconfigured or your computer clock is set to the
wrong time.
It’s likely the website’s certificate is expired, which prevents Firefox
from connecting securely.
What can you do about it?
protokolle.zapf.in has a security policy called HTTP Strict Transport
Security (HSTS), which means that Firefox can only connect to it
securely. You can’t add an exception to visit this site.
The issue is most likely with the website, and there is nothing you can
do to resolve it. You can notify the website’s administrator about the
problem.
