Question Do I need to disable or uninstall UFW and Fail2Ban before installing Plesk Obsidian?

[Rendor9]

Server operating system version

ubuntu 24.04.4

Plesk version and microupdate number

18.0.76

Hello, I have a question about installation. If I have a freshly installed server with only basic hardening in place, with UFW firewall and Fail2Ban both active, can I install Obsidian directly, or do I need to disable (or uninstall) these components before installing? I want to avoid any conflicts during the installation. Thanks

It is not necessary to uninstall UFW before installing Plesk Obsidian on a new Ubuntu 24.04 server.
However, I recommend temporarily disabling UFW before starting the Plesk installation, or making sure that all required Plesk ports are allowed. This helps prevent the installation process or the initial access to the Plesk panel from being blocked by the firewall.
You can disable UFW temporarily with:

sudo ufw status
sudo ufw disable
