Yes, same behavior ...

Appr. 2 sec., so the -t option didn't help too ...

All right, it works with wget:

monitor2-lx:/usr/local/nagios/libexec # wget https://10.35.178.154/
--15:10:47--  https://10.35.178.154/
            => `index.html'
Connecting to 10.35.178.154:443... connected!
HTTP request sent, awaiting response... 200 Ok
Length: unspecified [text/html]

     0K .

Does this give you a clue?

Regards, Jens
