Socket error

Does anyone know if the Ftpapi newsgroup is still active?
I haven't gotten a message from that group in a long while.
I looked at the site, their archives only go through 2018.

I sent this message to that group last week but I don't know if it went anywhere:

I'm getting this error doing a http_url_post_stmf.
(GSKit) I/O: A connection with a remote socket was reset by that socket.
(GSKit) An operation which is not valid for the current SSL session state
was attempted.

This process seems to be working for many of our vendors and failing only for one vendor.
I'm not sure what to do to diagnose this issue, or if the problem is on the vendor's end.
Any suggestions would be appreciated.

Below is the debug log.
Regards,
Charlie
