Error using dellemc_device_check.py on PowerVault ME4012

I used dellemc_nagios_discovery_service_utility.py --host=192.168.192.12 --http.user=login --http.password=geheim --http.port=443 --http.timeout=30 --http.retries=1

That gave me the cfg File with the command

dellemc_device_check.py --devicetype=ME4 --componentname=Subsystem --protocol=2 --http.user=login --http.password=encryptedPW --http.timeout=30 --http.port=443 --http.retries=1

dellemc_device_check.py comes with an error:

Unable to get status information due to technical issues

What do i miss here?

Thank you and best regards
