I have a problem with jdisc integration.
I would like to connect Jdisc to I-doit.
But I have the following error messages:

Common settings:
Could not establish connection: "Could not establish connection: "Database error: SQLSTATE[08006] [7] could not connect to server: Permission denied Is the server running on host "@IP" and accepting TCP/IP connections on port 25321? ". Please check your configuration of the selected jdisc server.". Please check your configuration of the selected jdisc server.

Discovery settings:
The connection to JDisc Web Service could not be established. Please check whether the settings are correct and that the web service is up and running

I test the connection to the PG database from a server other than the I-DOIT server with PgAdmin, and the postgresro account, it's functional.
I test the connection to the following url : https://@IP with the DOMAIN\myaccount account from a server other than that of I-DOIT, it's functional.

On the I-DOIT server, I disabled the firewall, but that doesn't change anything.
When I do an nmap on the two ports I get this result:

[@~]$ nmap -p 443 @IP
Starting Nmap 7.70 ( https://nmap.org ) at 2024-01-09 09:40 CET

[@~]$ nmap -p 25321 @IP

PORT      STATE SERVICE
25321/tcp open  unknown

Nmap done: 1 IP address (1 host up) scanned in 11.04 seconds

When I do a curl on the url I get a result.

On the Jdisc server I don't have a firewall.

Where can I find logs related to jdisc modules?
What package do you need to use jdisc in i-doit?

Idoit serveur : RHEL 8, I-doit pro 28
jdisc version : Jdisc Discovery 5.0 - Professional Edition - build 5179

Thank you for your answers.
