Hi, After quite a while without any problems I am now hitting this issue again (no tampering with extensions or anything at all -- system untouched):
2024-03-15 07:34:08,879 [https-openssl-apr-8543-exec-8] ERROR o.a.g.rest.RESTExceptionMapper - An internal error occurred, but did not contain an error message. Enable debug-level logging for details. 2024-03-15 07:34:08,879 [https-openssl-apr-8543-exec-8] DEBUG o.a.g.rest.RESTExceptionMapper - Unexpected error in REST endpoint. java.lang.NullPointerException: null Restarting Apache Tomcat and that alone solves the problem. Any ideas?

Hi, No, I'm the only admin with access to the Guacamole system, and nothing has been moved around. In fact, I haven't even logged into the system for a month, and it has been working fine until recently users could open a "blank" page from the Guacamole URL but not log in via SAML IdP. In other words, the web app would immediately fail as the user couldn't load the remote IdP auth page.
