    Hello

     

    Thank you for your answer, I think an update on the server broke the monitor. I have a 403 error that denies me access to the application

     

    curl --head HTTP/1.1 403 Forbidden Date: Tue, 28 Aug 2018 22:35:29 GMT Server: Apache/2.2.15 (Red Hat) Connection: close Content-Type: text/html; charset=iso-8859-1

     

    curl --head --http1.0 HTTP/1.1 403 Forbidden Date: Tue, 28 Aug 2018 22:34:46 GMT Server: Apache/2.2.15 (Red Hat) Connection: close Content-Type: text/html; charset=iso-8859-1

     

    This error message may mean that you can not access a page because of a missing password.

     

    Regards
