I suspect the connection is closed by the remote, but hackney doesnt know how to handle this?

hi @benoitc I see you added this tho a milestone, that means it's a confirmed bug or what?

[benoitc]

it means i will ensure to close it this week :) Have been a bit more side tracked than expected but will maintain a release sometimes this week.

@benoitc great, take your time. Thanks!
