Steps to reproduce:

• active agents (no passive checks) + TLS activated between agents and proxies
• active proxies + TLS activated between proxies and server

Result:

"process_auto_registration_contents(): 4 is not a valid value for tls_accepted" flooding zabbix-server logs.

zabbix-server switched in debug level=4 to get more info:

Questions:

• Looks to be an issue at autoregistration level when TLS is activated? How to solve this?

• Otherwise, no real  need of active agent autoregistration ... is there a way to disable it?
