GLPI-Agent-1.7.1-x64 Missing cookie & No supported answer from server

Hi!

Yesterday, I updated GLPI to its latest version (10.0.13) and decided to switch the inventory collection method from OCS to Native. To this end, I manually installed GLPI-Agent-1.7.1-x64 and GLPI-AgentMonitor-x64 on one of the computers in our network. However, when I attempted to forcibly execute the inventory collection through the Monitor, I encountered an error log as shown below.

After an initial analysis, I was unable to determine the cause of this error, especially since the default browser being used does not have cookies disabled.

I don't see this message anywhere in the GLPI code. Do you have something configured in front of your GLPI like a proxy or SSO that might be giving this response instead?

Yes, my GLPI uses SSO to authenticate the 900+ users we have on our network.

Could it be my SSO that is generating the communication error with the server?

Maybe. You should disable SSO for that specific URL if possible. If you want, you have the ability to force HTTP basic authentication instead for that URL in your web server config and then install the agents using the User and Password configuration options (not sure how to set these after the agent is already installed).

I disabled SSO to check if it would work, but another error occurs, as seen in the log below.

[Mon Mar 18 09:36:54 2024][error] [http client] communication error: 403 Forbidden
[Mon Mar 18 09:36:54 2024][error] No supported answer from server at https://[domain_name]/marketplace/glpiinventory/

In my URL https://[domain_name]/front/inventory.conf.php I have the Enable Inventory option Active

I found it strange that it was an HTTP error and not HTTPS, since it is a secure server.
