Site over https DynDNS not avaiable

i got a raspian + apache2 + ssl and dynDNS

The forwarded dyndns works on http, but the site is not avaiable over https and i don't know why... If i try the same on local net everything seems to work correct. i got a prompt over https to accept the cert.

I think the proplem should be found in /etc/apache2/sites-available/default resp. /etc/apache2/sites-available/default-ssl

It's hard to know without knowing a little more about your SSL certificate. Your Apache configurations look fine to me, although I am admittedly not an Apache pro (but I have certainly done my fair share).

My first suspicion would be the certificate - if your certificate includes your IP address, clearly your browser will be upset that the IP in the certificate is not the IP you're connecting to. That would be my first guess at the problem, but it could be something else.

Where did you get your cert? What information is included as part of it? Is that SSL vendor supported by your dynamic DNS vendor ( You're not using a self-signed certificate, are you?

You might check out's FAQ here. Even if you're not using's service, this might shed some light.

Separately, if you have openSSL, you can check your certificate to see what information is included in the cert, and check if any of it might be impacted by a dynamic IP address.

openssl x509 -in certificate.crt -text -noout
