Issue with TCP test for HTTPS

[Guillaume François]

Hello,

I'm using the last version of Monit 5.25.3 on a CentOS fully upgraded but since some updates I'm having an issue with this test on Apache HTTPD

if failed port 443 protocol https with timeout 15 seconds for 3 times within 5 cycles then alert

raising error:

[CEST Jul  3 15:05:00] warning  : 'apache-ns353666-prod' failed protocol test [HTTP] at [localhost]:443 [TCP/IP TLS] -- SSL server certificate verification error: unable to get local issuer certificate

I use Monit binaries from the website and not the distribution packages (https://mmonit.com/monit/dist/binary/5.25.3/monit-5.25.3-linux-x64.tar.gz)

Also openssl version from OS is "OpenSSL 1.0.2k-fips  26 Jan 2017" but it should be an issue as openssl from with the binaries if I'm not wrong.

Do anyone have some clue how to make it work again ?

Regards.
