I can't, not more than to use CURLOPT_VERBOSE. Someone should add better
tracing abilities to PHP/CURL. I always recommend using the curl command line
tool for that reason.

Well, it matters to you since the server most likely works with one of the
ways and possibly not with the one you pick at random.

With ftp-ssl enabled? If so, what's the problem?

ftps:// connects to an ftps server, not to a ftp one as you ask for an
immediate SSL connection then and ftp servers don't do that.

I.e ftps is usually used to port 990 and it makes use of SSL immediately.

ftp:// with ftp-ssl enabled usually connects to port 21 to uses FTP commands
to negotiate switching to SSL-use.
