Steps to reproduce:
- Use Zabbix server 4.4.0alpha1 or alpha2 (zabbix_server (Zabbix) 4.4.0alpha2 Revision 36f514195c 19 August 2019, compilation time: Aug 15 2019 10:07:23)
- Debian 10 server
- Use repo deb http://repo.zabbix.com/zabbix/4.3/debian buster main
- Create a new web-scenario under a host.
The newly create web-scenario does not start to monitor. An older web-scenario created under Zabbix 3.x is still working but newly creates ones don't start monitoring. The "Web monitoring" widget in the Dashboard shows status 'Unknown' for these broken web-scenario's.
The zabbix_server.log doesn't show any relevant information.
