Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: digital.lernzeit.org

I ran this command: nothing

It produced this output: over local network no problems, over mobile network (4G)

My web server is (include version): apache

The operating system my web server runs on is (include version): ubuntu 18.04

My hosting provider, if applicable, is: contabo

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Hello,

If I am using my ios client to access my website over a local LAN connection everything works fine. But after a change to the mobile network I cannot access it. Chrome shows the message „ ERR_SSL_PROTOCOL_ERROR“ and Safari „no server response“. Also I use the HotSpot of my ios device it doesn`t work with Mac, ios, Windows and Android.
If I use the HotSpot of my android device it works without any errors from all other systems.

I really don`t know what is missing or incorrect.
Thanks for help and with best regards
Stefan

Hi @Strahlemann85

that's simple, see your check, one day old - https://check-your-website.server-daten.de/?q=digital.lernzeit.org#url-checks

You have ipv4 and ipv6 ip addresses.

But your ipv6 doesn't answer, timeouts.

So:

  • remove your ipv6 AAAA record (bad, ipv6 is the future)
  • fix your webserver, so ipv6 works

PS: So if a client uses ipv6, it doesn't work.

Hello Juergen,

thank you very much. Your are absolutely right...I forget to configure ipv6 and not mentioned it because only my ipad uses ipv6 over mobile data. :see_no_evil:

And I overread it in the domain check from yesterday I made.

I will change my configuration of the apache to dual stack und try again.

Thank you and with best regards
Stefan
