API is enabled but cannot be reached because it says it is disabled

I have updated to version17.10.8918 and the API is set to true in config.php. When I try to access the API via either web browser or using curl

curl -k -u user:pass https://observium.iops.pivotal.io/api/v0/devices/

The API is disabled

We noticed this with the previous version that we were running so I upgraded to see if it was something that was fixed but we still receive the disabled notification.

Settings from config.PHP

// Enable the API

$config['api']['enabled'] = 1;

$config['api']['module']['inventory']   = 1;    // enable or disable the inventory module

$config['api']['module']['billing'] = 0;    // enable or disable the billing module

$config['api']['module']['packages']    = 1;    // enable or disable the packages module
