Change log level to info for connector exceptions

These errors in resolve_remote_id aren't really errors, they're
routine problems that we can expect from dealing with the outside world,
like a connection timeout, a server being down, a server being blocked,
et cetera. It's cluttering up the logs and causing unnecessary worry.
