Logging into your GLPI installation from Gapp (A GLPI app) is not possible due to this error message: Trust anchor for certification path not found


As for Android Java reference CertPathValidatorException:

An exception indicating one of a variety of problems encountered when validating a certification path.

The most usual problem is a self-signed certificate or a badly configured SSL web server.

Additional info:


  1. If your GLPI installation is not published on the Internet, you won’t be able to get a proper SSL certificate. Drop https and use for http.
  2. If it is exposed to the internet, you need to properly configure your webserver. Go to and configure it to get an A.


->  New Gapp 1.2 with GLPI 9.5 support
