So it is sent by the server and received by your computer but libcurl doesn't
"see" it?

... but this response is found and recognized?

If you hadn't mentioned that 421 thing, I would've guessed that your control
connection simply was killed by a middle man, like a firewall or NAT.

But also, getting the 421 through but missing the 226 seems like something
wonderfully weird I suspect either I or you have misunderstood something...
