      Description

      After upgrading Zabbix Agent and Server to 4.4.2 this morning, the agent starts crashing as long as the Server is reachable for them. This affects remote agents as well as the agent installed on the server itself. Even the last one uses psk, as I streamlined the configuration as much as possible.
