Steps to reproduce:

1. upgrade from rhel7 x87: 6.0.33 to 6.0.34 https://repo.zabbix.com/zabbix/6.0/rhel/7/x86_64/
2. zabbix agent no longer starts with error "cannot use encryption configuration: encryption support was not compiled in"

My config file (with comments and blank lines removed):

PidFile=/var/run/zabbix/zabbix_agent2.pid
LogFile=/var/log/zabbix/zabbix_agent2.log
LogFileSize=0
Server=zabbix.myhost.com
ListenIP=10.1.9.162
ServerActive=zabbix.myhost.com
HostnameItem=system.hostname
HostMetadataItem=system.uname
Include=/etc/zabbix/zabbix_agent2.d/*.conf
ControlSocket=/tmp/agent.sock
TLSConnect=psk
TLSAccept=psk,unencrypted
TLSPSKIdentity=AgentPSK01
TLSPSKFile=/etc/zabbix/psk/zabbix-agent.psk
Include=./zabbix_agent2.d/plugins.d/*.conf
 

Result:

agent starts and outputs the above error "cannot use encryption configuration: encryption support was not compiled in" and immediately terminates.

Downgrading to 6.0.33 immediately resolves the issue.

Happy to provide any further information if required, I'm not looking for support to get it working just an FYI. Thank you
