Change Base Type HTTPS to HTTP back

Expected behavior:

  • Hi, i set up zammad today on debian 11 with apache 2 with ssl.

Everything worked fine until i changed the type http to https in the gui.

After that i got a lot of CSRF errors. I thought, if its running fine on ssl i can change the button to https, but wrong.

Actual behavior:

  • I found the solution for my problem, but i dont know how to fix it, because i cant login to gui. I need to set back the base type from https to http.

Like in this Ticket, but i dont use Docker:
CSRF Authentification failed - Technical assistance - Zammad - Community

Is there a way to change the type back from https to http to get it run again?

Finally was able to fix it, with another ticket:

In your active apache2 conf - /etc/apache2/sites-avaible/zammad.conf you have to put the following lines at the end but before closing the Virtual Host Tag.

After reboot it should work again.

RequestHeader set X_FORWARDED_PROTO ‘https’
RequestHeader set X-Forwarded-Ssl on
