Resolved When trying to configure a Mailman 3 list I get a 404 error

[Alain Ronce]

Server operating system version

Debian 12.11

Plesk version and microupdate number

Plesk 18.0.72

Hello
On a fresh installed server with Debian 12, I have now Mailman 3, the function "Manage list" available on the right of the line in Plesk interface "Mail, Maililing list" I get an error "404 Not Found"
The address is : lists.domain.ext/mailman3/postorius/lists/mylist.domain.ext (note: mylist domain ext are example)
The requested URL was not found on this server.
Apache Server at default-00-00-00-00 Port 443
The same result on port 80
I understand I have a problem with Apache, I have a new installation and I don't understand where is the problem.

Ps: I've read a message with a quite similar problem, but the discussion provides technical elements concerning Apache configuration, rather than a real solution for me.

Over SSH, can you check if the module is enabled?

apache2ctl -M | grep proxy_uwsgi

If you have no output, you can try to enable it:

plesk sbin httpd_modules_ctl -e proxy_uwsgi

Unfortunately, I have checked and the module proxy_uwsgi is enabled, I can also find the socket uwsgi.sock indicating the installation is ok, something else is ko somewhere.. . I have another server with Debian 10, and I'm obliged to migrate it to Debian 12 (with an automatic process provided by the company that gave me the server. Indeed, with Debian 10, updating Plesk is now impossible. I'm afraid to lose all the mailing list on this server !
I now imagine finding another solution to replace Mailman 3. Plesk provides a very simple interface to create lists (only members), it is largely insufficient

(+) I'm using Let's Encrypt, in that case le component lists.xxx is not protected with this kind of certificate, at the same time Plesk link to manage lists try to connect on https 443. Could this be my problem?

Alain, can you please also confirm if the cgid module is enabled?

 

[Alain Ronce]

Thank you for your answer.
I confirm that le cgid module is enable :

root@ns3018436:~# apache2ctl -M | grep cgid
cgid_module (shared)
fcgid_module (shared)

I also tried to check the content of /etc/apache2/plesk.conf.d
I didn't see anything strange, but...

Best regards

Thank you for your update and confirmation. I would suggest opening a ticket with Plesk support for further investigation directly on the server. To sign-in and open a ticket please go to:

• https://support.plesk.com

If you got your license from a reseller, your reseller is in charge of providing you with support. You can raise the inquiry with them and they can forward it to our team for further processing.If the reseller does not provide support, here is an alternative to get support directly from Plesk:

Hello,
Finally, I successfully accessed the Mailman administration web interface (Postorius). Everything I have tried before was unsuccessful, so I decided to reinstall the server, including Linux Debian 12 and Plesk. That was my last chance! and miraculously everything became operational, but I don't know why... I have no explanation.
Thank you all for the help
