Retrying. --8<---------------cut here---------------end--------------->8--- The server keeps closing the connection prematurely. Unlike our client in Guile, wget keeps retrying and so, little by little, it eventually gets more bytes. In my case it seems to get stuck at 90% though, where each attempt gives it zero or very few additional bytes. I suspect this is an issue at SWH. I’ll bring it up there. Thanks, Ludo’.
