HTTP-Response-codes starting with 4 (like 404) are indicating that
a resource being requested can't be found or is missing due to
other reasons.

HttpUrlConnection is throwing an exception in this case. Check your
URL or look into the server's log-file what has been requested and
what the request should look like.

Doesn't matter very much in this case.

Just guessing: Is the resource-handler not available for localhost and
maybe just for the "real" address?

Just a sidenote: This text is irrelevant and lead to no obligations for
the recipient of the mail whatsoever.

Just another sidenote: This exclusion of liability is irrelevant
as well. If your company is spreading viruses and it lead to
damages on the receiving side, your company has to pay for the
damages.
