# Missing Credentials for Device

Several methods open a CLI connection with the device against which NetMRI_Easy runs, thus requiring CLI credentials for that device. If the NetMRI instance running the script is missing those credentials, you may see the following error:

`**Error / `NetMRI` dis-sessions/dis-error % No auth credentials found for device 18[ ``http://u.x.y.z/api/3.3/cli_connections/open.json`

The URL stated is the URL for the NetMRI Core API method that failed. The cited IP address is the IP address of the NetMRI instance.

> ⚠️ `Job_id` in the Perl sandbox is the JobDetailID as used by the NetMRI API.` Batch_id` is the Job ID used by the NetMRI API.
