Hello Dieter,
No, it is not possible to log %E to access.log, and the errno-based
%E itself is often useless in such situations, especially in the
official code where it is often lost or stale.
However, your use case _is_ valid, and Factory is working on improving
detailing of various connectivity problems similar to the ones you are
talking about. There is no official pull request yet, but we are getting
very close. If you would like, please feel free to test-drive our
master/v6-based https://github.com/measurement-factory/squid/pull/63
HTH,
Alex.
