There was a problem hiding this comment.
I think a OperationalError is more at its place here.
This also applies to the other places where you wrap this exception, otherwise it would not be captured by other frameworks like sqlalchemy.
Before this change if a user needed to catch connection errors (e.g. connection refused) they needed to add a dependency on requests and import the relevant exception from requests.exceptions module. After this change all requests exception get rethrown as a TrinoConnectionError instead.
