You should see info about SSL by running xymonnet --version (for example):

[server/opt/xymon-4.3.12/server/bin] ./xymonnet --version
xymonnet version 4.3.12
SSL library : OpenSSL 0.9.7d 17 Mar 2004 (+ security fixes for: CVE-2005-2969 CVE-2006-2937 CVE-2006-2940 CVE-2006-3738 CVE-2006-4339 CVE-2006-4343 CVE-2006-7250 CVE-2007-5135 CVE-2007-3108 CVE-2008-5077 CVE-2008-7270 CVE-2009-0590 CVE-2009-2409 CVE-2009-3555 CVE-2010-4180 CVE-2011-4576 CVE-2011-4619 CVE-2012-0884 CVE-2012-1165 CVE-2012-2110 CVE-2012-2131 CVE-2012-2333 CVE-2013-0166 CVE-2013-0169)

It looks like xymonnet does not use ssl


 ldd `which wget` | egrep "ssl|crypto" ; echo $?
        libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007f5a5b183000)

As I had wrote some time ago - I am sure I had repied Yes to use SSL during xymon installation.
And I had reinstalled again on other machine to double check, but with the same result.

So, it looks like problem is with installation process.
Here is "ssl" grepped from make log. May be this will help:

Note: I had replaced in e-mail real server IP with ==XYMON_HOST_IP_REPLACED==.

Problem is for some sites with valid certificates too.
I had checked to access page with wget or lynx - and it is working.
So I do not see reason why Xymon should get "Server Timeout"  for the same target.

Here is the debug of wget. Please, advice how to diagnose/debug Xymon to find the solution.
I am a bit confused why nobody reporting the same problem:
* nobody using new openssl libraries?
* nobody do https tests for some, may a bot non-standard SSL certificates or web-sites?

You might just be unlucky.  If half of all websites have implementations that trigger the problem, and if half of all Xymon installations have the buggy openssl library, then only 25% of people will get the problem.  Given that not all Xymon users test https websites, and of those, not all of them are subscribed to The List, the odds drop off very quickly.  Oh, and my first guesses of half websites and half of openssl installs used for Xymon is almost certainly very high. The proportions might be closer to 10%.  So the odds are against you finding someone else on The List with the same symptoms.

Try the following:

ldd `which wget` | egrep "ssl|crypto"
ldd ~xymon/server/bin/xymonnet | egrep "ssl|crypto"
ldd `which openssl` | egrep "ssl|crypto"

If the libraries used by the two tools are different, then you should not be surprised to get different behaviour.

Try configuring a known good website on the Internet in your https monitoring.  I'm guessing that https://www.xymon.org/ would be OK.

Try to connect to the websites using openssl:

openssl s_client -connect epak.pmlp.gov.lv:443<http://epak.pmlp.gov.lv:443/>

If that times out, it might show a message to indicate why.
