Thank you Henrik, this is the root cause!
We did not install openssl dev package, the "bbtest-net --version"
only returns hobbit version.
After we installed and recompile, problem is gone!
Thanks again.

When hobbit monitors the https site, it always gets the error " HTTP
error 0" like below, I appreciate a lot if anyone can give the =
solution,
I'm with Aaron in same company, the weird thing is, if we use wget,
then =
can still receive data, so not sure what's wrong.
Can you try running '~hobbit/server/bin/bbtest-net --version' just to
check the version number of your OpenSSL library ?
And can you get data using just the openssl client utility ? Like this:
openssl s_client -connect 10.20.30.40:443
(replace the IP with that of your server). If that succeeds and shows
you the server certificate then enter
GET / HTTP/1.0
and hit <enter> twice - this mimicks a simple HTTP request. Does that
work ? And how long does it take to complete ?
Finally, you could try modifying the code in
hobbit-4.2.0/bbnet/contest.c In there is a routine called
"socket_read"; delete the version in your file and replace it with the
version below. Recompile with "make bbnet-build"
and copy the new bbnet/bbtest-net program to ~hobbit/server/bin/ .
Then run it with the "--debug" option enabled, like
bbcmd bbtest-net --noping --debug HOSTNAME
to run the test of just this one host. Hopefully that will print out
some more info about what happens with that read that returns -1.
