The following is a list of the connection exceptions that can occur in Neo4j.

22+
Connection exceptions occur when the client is unable to connect to the server for various reasons such as network issues, server-side routing being disabled, or the database being unavailable, etc.

15-
These errors are detected by the server and are usually related to some kind of database unavailability, such as limits reached, out-of-memory, timeouts, etc.

The error can be temporary and could therefore succeed if retrying the request.
