When minio runs with MINIO_CI_CD=on, it is expected to communicate with the locally running SUBNET. This is happening in the case of MinIO via call home functionality. However, the subnet-related functionality inside the console continues to talk to the SUBNET production URL. Because of this, the console cannot be tested with a locally running SUBNET. Set the env variable CONSOLE_SUBNET_URL correctly in such cases. (The console already has code to use the value of this variable as the subnet URL)
