Stuck on installation of icingaweb2


I’am trying to install Icinga2 with icingaweb2 on RHEL9. I walked trough the Installation documentation from Icinga.
I’m stuck at the position where I enter the setup token and press next. The following page appears.
Honestly I don’t know which step I missed.
Hopefully somebody can help me out of this.

Give as much information as you can, e.g.

  • Icinga Web 2 version : 2.11.4-2.el9
  • Used modules and their versions (System - About)
  • Web browser : Firefox
  • Icinga 2 version used (icinga2 --version) version: r2.13.6-1
  • PHP version used (php --version) PHP 8.1.14
  • Server operating system and version: RHEL9




I took the longer way and did the the setup manually.

Now the loginscreen of Icinga appears but I can type in whatever I wan’t the same error like above appears after hitting “enter”.

Could it be that my combination of OS (RHEL 9) and PHP (8.1.14) is unsupported ?



Please have a look here.

Installing Server certificates and switching Apache to ssl are the solution.
