I installed privacyidea following this guide:
https://privacyidea.readthedocs.io/en/latest/installation/centos.html
After the final step of restarting httpd service, I could not access https://<privacyidea server ip adress>
It works after disabling firewall, so I thought maybe I should report. Maybe you consider adding a note about firewalld in the mentioned centos installation guide.
I am looking forward reading your documentation and test privacyIDEA Server.
Keep up the good work.
