@Jay Kumar SenSharma I am trying to understand the host registration process: Ambari Server : in Ambari Properties this is what I have: s ecurity.server.two_way_ssl=true On All the host machine Running Python 2.7.5, I have "force_https_protocol=PROTOCOL_TLSv1_2" in ambari-agent. INI On my EdgeNode, I have Python 2.6 and I have to DISABLE force_https_protocol=PROTOCOL_TLSv1_2 to make it work correctly. PROBLEM: I have One VM running SUSE LINUX 11 SP4. It's running Python 2.6, so I have this "force_https_protocol=PROTOCOL_TLSv1_2" DISABLED but I am not able to register his host using AMBARI. here is the log: INFO 2018-05-08 21:00:39,842 AlertSchedulerHandler.py:185 - [AlertScheduler] Stopped the alert scheduler.
