Issue Firewall Rules Management can not be enabled

[h-alf]

Hi all,

i have two servers that are just installed, both have the same problem.

when i click "Enable Firewall Rules Management" I get an error page. After reloading I get an permission denied, that's it.
Back to Start...

I'm attaching screenshots of what is happening, sequentially numbered.

The problem is the same on both servers. Both servers have the same hardware and software, same versions.

OS	Ubuntu 18.04.4 LTS
Product	Plesk Obsidian Version 18.0.26, last updated on April 15, 2020 11:08 PM

Does anybody know a solution?

TIA

I already did this: Cannot enable Plesk Firewall: The firewall rules management has not been enabled

Same issue.

Did somebody else have the same problem?

In which log can I see something for this error?

It seems i am having this, or a very similar problem. My firewall rules aren't being applied any more through Plesk Firewall Management. I've reinstalled the service twice, unfortunately no luck.

Did you happen to find a solution to this problem?

Can you please check under Tools & Settings > Custom View settings and make sure that "Firewall" and Extensions are marked.
If they are not marked, please mark it and click on "Apply".

Unfortunately I have the same problem. I set up a brand new server today with Ubuntu 22.04 LTS. I am using the Plesk web admin edition. I have already tried to reinstall the Plesk firewall but unfortunately I get exactly the error screen described above. How can I fix the problem?
Is the Plesk Firewall not included in the web admin edition?

Short update from my side: I was able to solve the problem by first enabling the Plesk Firewall Rules manually via CLI. For this purpose I executed the following command:

sh /usr/local/psa/var/modules/firewall/firewall-new.sh

After that I was able to activate and even deactivate the management in the GUI without any problems. The IP tables have been adjusted accordingly and everything works fine.
I don't know why it worked like this but now everything is fine.
