An automation job calls a retrieve-data API for switch inventory. One failure shows a connect-timeout with errno in the client log; another shows HTTP 400 with a body complaining about a bad template field. How should these be classified for next action?

Short Explanation
A locked door (never connected) is different from a clerk who opened the door and refused your form. Timeouts and errno point at the path; status-plus-body points at your request. Log fields decide the next wrench you grab.
Full Explanation
Connect-timeouts and transport errno indicate the client never completed a healthy exchange with the API endpoint. An HTTP 400 with a template-field complaint means the server processed the request and rejected the application payload. Those classes drive different remediations—path/reachability versus request content—without jumping into retry-policy design yet.
