zabbix 6.0 (Ubuntu 20.04) reports an error when using https to monitor the server hardware (redfish protocol), Cannot perform request: error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small.

I am using curl to test and also report the error

curl: (35) error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small

After checking the resource online, it is because openssl disables the low security encryption method. Just change the openssl parameters, restart the zabbix related services or reboot the system after the change.

sudo nano /etc/ssl/openssl.cnf

openssl_conf = openssl_init

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
CipherString = DEFAULT@SECLEVEL=1
