Is that the server you're describing or the client? What do you mean with "is
not working" ? What are you suggesting it should do that it doesn't currently
do?

Exactly because then the server returns a proper error instead of just not
sending any data.

Timeout is not working?

Do note that curl uses libssh2, libssh is a different project...

It's really simple: the server stops sending data. curl sits waiting for more
to arrive that doesn't come. The server could return an error but it doesn't.
