ssl warnings

[Pascal76]

Hello,
Could we get access to some issues like "unable to get local issuer certificate" ?
Ex: t.info.lynx-optique.com
https://www.sslshopper.com/ssl-checker.html#hostname=t.info.lynx-optique.com
Or error code like CURLINFO_SSL_VERIFYRESULT error codes in PHP
List is here : https://www.php.net/manual/en/function.curl-getinfo.php

something else strange :

try { $certificate = @sslcertificate::createForHostName($domain_, 15, false); }

Could not download certificate for host mea.global-cdm.net because Could not connect to mea.global-cdm.net:443.
While there is no issue checking with https://www.sslshopper.com/ssl-checker.html

PHP Warning: stream_socket_client(): Unable to connect to ssl://mea.global-cdm.net:443 (Unknown error) in /apache_sites/jbm/lib_8.2/vendor/spatie/ssl-certificate/src/Downloader.php on line 185

PHP Warning: stream_socket_client(): Failed to enable crypto in /apache_sites/jbm/lib_8.2/vendor/spatie/ssl-certificate/src/Downloader.php on line 185

also I often have false errors :
Error : emstrack.evaneos.it : The host named emstrack.evaneos.it does not exist.
Error : emstrack.evaneos.nl : The host named emstrack.evaneos.nl does not exist.
Error : static.evcdn.net : The host named static.evcdn.net does not exist.

while :

host emstrack.evaneos.it
emstrack.evaneos.it is an alias for emstrack-evaneos-it.emarsys.net.
emstrack-evaneos-it.emarsys.net is an alias for suite34.emarsys.net.
suite34.emarsys.net has address 217.175.192.43

host static.evcdn.net
static.evcdn.net has address 104.26.9.57
static.evcdn.net has address 104.26.8.57
static.evcdn.net has address 172.67.72.8
static.evcdn.net has IPv6 address 2606:4700:20::681a:939
static.evcdn.net has IPv6 address 2606:4700:20::ac43:4808

today :
The host named www.krysoutremer.com does not exist.
The host named news.samsung.com does not exist.
The host named www.meetic.fr does not exist.
The host named www.meetic.pl does not exist.
The host named www.meetic.pt does not exist.
:(
On my server I have installed the last "Unbound" for the dns resolution, and this still happens

From my debug, for mea.global-cdm.net,
I have this error :
error:0A000152:SSL routines::unsafe legacy renegotiation disabled in ...
and I have to do that :
OPENSSL_CONF=/tmp/openssl.cnf php myscript.php

with /tmp/openssl.cnf containing :

openssl_conf = openssl_init

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
Options = UnsafeLegacyRenegotiation
