Hello everyone,

 

I’m new here but using Centreon for a few years.

I recently installed the Infor ION Grid Monitoring Connector.

Https protocol, port and credentials are OK

CLI returns all the information I need with both application and node modes but the result can’t be displayed in the GUI, instead the UNKNOWN : 401 Unauthorized is displayed

The --debug option only adds a few strange lines such as :

=> Recv header: HTTP/1.1 401 Unauthorized

<td>HTTP ERROR: 401 Unauthorized

<p>Problem accessing /grid/rest/nodes

<pre id="message">Authentication failed - Invalid credentials</pre>

 

 

Centreon version is 25.10.9 (IT-100) and all plugins are up to date.

Does anyone have any ideas on how to resolve this issue ?

Best Regards

 

Olivier
