There was a problem hiding this comment.
Possible future enhancement: store a vector of errors and throw a single, composite error that encompasses them all.

Motivation
If we can't establish a connection to a remote for the user, we will retry to create the connection. Eventually the requests connection timeout will fire, and we will fail the request. Right now we fail the request always with the
HTTPClientError.getConnectionFromPoolTimeouterror. While this is very descriptive, it does not tell the user if there are to many waiting requests or if there was a connection problem.Changes
Result
If user have a typo in their url, they will get better errors. (dns failure)
