Steps to reproduce:

1. Set up FreeBSD Server
2. Install Zabbix Agent
3. Set up config file the same way as for a Linux client

Result:

zabbix_agentd [1027]: "TLSConnect" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd [1027]: "TLSAccept" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd [1027]: "TLSPSKIdentity" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd [1027]: "TLSPSKFile" configuration parameter cannot be used: Zabbix agent was compiled without TLS support

• Same result for the agent with openSSL as well as GnuTLS as found at https://www.zabbix.com/download_agents?version=6.4&release=6.4.3&os=FreeBSD&os_version=13.1&hardware=amd64&encryption=GnuTLS&packaging=Archive&show_legacy=0
• Same result using Agent 6.0.18
