• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

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

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
