Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.

Sometimes I see websites with EV-certificates - oh, then they forget to renew the certificate and the certificate is expired. That’s really bad. Then the website doesn’t use HSTS, so users can create an exception. Happens sometimes, big companies (bundesfinanzhof in Germany).
