CSF error on new install - AlmaLinux 8.5 & Ubuntu Server 20.04.3 LTS

Error displayed when clicking on Firewall Configuration of CSF:
It looks like the webpage at https://hostname.domain.com:8090/configservercsf/iframe/ might be having issues or it may have moved permanently to a new web address.

Steps to reproduce:

1. Install CyberPanel on AlmaLinux 8.5 or Ubuntu Server 20.04.3 LTS
2. CyberPanel menu: SERVER > Security > CSF
3. Install CSF
4. CyberPanel menu: SERVER > ConfigServer Services > ConfigServer Security & Firewall
5. Click on “Firewall Configuration” under csf - ConfigServer Firewall

New installation of OS & CyberPanel - latest version.

See Github Issue: CSF error on new install - AlmaLinux 8.5 & Ubuntu Server 20.04.3 LTS · Issue #776 · usmannasir/cyberpanel · GitHub

Workaround is to open CyberPanel in Inprivate/Incognito browser window.

Has anyone installed CyberPanel on AlmaLinux 8.5 or Ubuntu Server 20.04.3 LTS and CSF > Firewall Configuration works for them?

Working very fine for me. I am using Almalinux 8.5 with Cyberpanel 2.1.2 latest version.
