It is being done properly. See:

https://portal.mozz.us/gemini/gemini.ucant.org/?crt=1

and

$ printf "gemini://gemini.ucant.org/\r\n" | openssl s_client -ign_eof -connect gemini.ucant.org:1965
...
closed

yeah sorry, the cases I'm worried about are when there's a timeout or error, server-side, rather than the default case.

Thanks for the tip re detecting the condition!
