    Description

      Zabbix 5.0.0. Installed with packages.
      Default zabbix_agent2.conf.

      Steps to reproduce:

      1. openssl rand -hex 32 > /etc/zabbix/zabbix_agent2.psk

      Added:

      TLSConnect=psk
      TLSAccept=psk
      TLSPSKIdentity=PSK10084
      TLSPSKFile=/etc/zabbix/zabbix_agent2.psk

      Restart zabbix agent.

      Encryption works without problems.

      Add to zabbix_agent2.conf:

      EnablePersistentBuffer=1
      PersistentBufferFile=/var/lib/zabbix/buffer.db

      Result:
      zabbix_agent2.log:

      The remote agent is the same.
