[SR-Users] Diameter_authorization_rejected (FHOSS)

Hello sr-users, i use the guide for "how to integrate an IMS using Kamailio with open5gs EPC" from Supreeth Herle. When my CotsUE(ONEPLUS8) try to Register. I get an 403 Forbidden HSS Authorization Rejected (see udp-stream.txt). The output of the fhoss looks like this. de.fhg.fokus.hss.cx.CxFinalResultException: Diameter_Authorization_Rejected at de.fhg.fokus.hss.cx.op.UAR.processRequest(UAR.java:134) at de.fhg.fokus.hss.main.Task.execute(Task.java:169) at de.fhg.fokus.hss.main.Worker.run(Worker.java:66) Insufficient access rights for the mysql hss_db? The user hss@localhost and hss@% have grant access. Maybe someone has had the error and has a hint and can help. Can't find the error. Many thanks in advance for an answer. -M.Wilmes
