I was using --retry-connrefused and --retry-on-host-error, however wget still exited on network issues with the above message.
I'm wget'ing via a rather unstable route so I need wget to retry on these network issues but it didn't. (Well, I can retry the whole command outside wget, but isn't it nice that wget could do this since wget has great support on retrying?) -- Best regards, lilydjwg
