Question Error applying firewall configuration despite of changing almost nothing

[King555]

Server operating system version

Ubuntu 24.04.3 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.75 Web Admin Edition

I wanted to change a little thing in my current firewall configuration and every time I want to apply this new configuration I get this error:

Error applying firewall configuration.
Command '['/usr/local/psa/var/modules/firewall/firewall-new.sh']' timed out after 14.999709844589233 seconds

I guess it means that the browser cannot reach the server/Plesk after applying the rules and then Plesk reverts the settings.

But the current configuration works fine/as intended and I changed only one rule. I removed one country code from this rule – the rule contains about 20 countries, which are being blocked.

What could be the problem here?

Nevermind, the solution was this entry in the panel.ini:

[ext-firewall]
confirmTimeout = 30

I guess it means that the browser cannot reach the server/Plesk after applying the rules and then Plesk reverts the settings.

I means Plesk cannot apply the new firewall setting within the default time frame (15 seconds) and reverts to the old firewall settings. This can occur when server (or VPS node) resources are strained.

Solution: increate timeout setting for firewall.
