Hey Sven,
Try setting the Environment Variables IPV to 4, this fixed it for me.
https://github.com/netdisco/netdisco/wiki/Environment-Variables#ipv
This is what the correctly set env variable should look like
~ $ printenv | grep IPV
IPV=4

Hi Charles,

Thank you for the quick response. That did the job for me, too.
So, they changed the default value of the IPV environment value from the

Best regards,
Sven
