Hi ,
I'm having problems enabling Plesk Firewall.
I installed Plesk Firewall, but it does not activate and gives the following error.
I can't even edit the rules in the panel.
What is the problem?

Failed to apply the firewall configuration.
- I did not receive connectivity confirmation after applying new firewall configuration, then same happened after I reverted to previous configuration. This means that both new and previous configurations were bad. Emergency rollback to configuration without rules was performed. Firewall is now disabled. Fix your rules and try again.
I can't even edit the rules in the panel.
