Data Connection Failure error code

Hello, I am sometimes encountering the following error codes when attempting to connect to a network: disconnection_code: 2 disconnection_reason: 14 failure_code: 0 failure_type: 0 I think that disconnection_code: 2 means Internal Call End Reasons according to this document: Platform specific error codes - Legato Docs Would you have a solution on how to understand this error code and potential ways to connect successfully when it happens please?
