Checks don't work with PSK encryption

[UglyAnimal]

I get an error in zabbix-server log when encryption is enabled for zabbix-agent:

connection of type "unencrypted" is not allowed for host

I get that error when following settings are defined in zabbix-server for host:

Connections to host: PSK
Connections from host: PSK

If I additionally define:

Connections from host: No encryption

Checks start working fine.
Is there any way to forcefully use encryption?

I use zabbix-server 4.0.15 and zabbix-agent 4.0.12-1.
