A valid Root CA Certificate could not be located, the certificate will likely display browser warnings

i'm trying to get Telegram Webhook working with my local machine but it doesn't make requests. I think it's bc of certificate issue

Here's what geocerts.com/ssl-checker says:

Here's my Apache config:

<IfModule ssl_module>
<VirtualHost *:%httpsport%>

    DocumentRoot    "%hostdir%"
    ServerName      "%host%"
    ServerAlias     "%host%" %aliases%
    ScriptAlias     /cgi-bin/ "%hostdir%/cgi-bin/"

    SSLEngine       on
    #Header always set          Strict-Transport-Security "max-age=94608000"

    SSLCACertificateFile       "%sprogdir%/userdata/config/cert_files/xxx/xxx-rootCA.crt"
    SSLCertificateChainFile    "%sprogdir%/userdata/config/cert_files/xxx/xxx-bundle.crt"

    SSLCertificateFile          "%sprogdir%/userdata/config/cert_files/xxx/xxx-server.crt"
    SSLCertificateKeyFile       "%sprogdir%/userdata/config/cert_files/xxx/xxx-server.key"

    SetEnvIf User-Agent ".*MSIE [1-5].*" \
    nokeepalive ssl-unclean-shutdown \
    downgrade-1.0 force-response-1.0

    SetEnvIf User-Agent ".*MSIE [6-9].*" \
    ssl-unclean-shutdown

    <FilesMatch "\.(cgi|shtml|phtml|php)$">
        SSLOptions              +StdEnvVars
    </FilesMatch>

    <Directory "%hostdir%/cgi-bin/">
        SSLOptions              +StdEnvVars
    </Directory>

</VirtualHost>
</IfModule>

I've generated these certificates with a following script:

: Version 1.0
: Author unknown (improved by Kama - wp-kama.ru)
@echo off

: parameters
set DOM=xxx.info
set DOM_KEY=xxx
set APACHE_VER=Apache-PHP-7.2-x64

: create .txt config file
set config_txt=generate-temp-config.txt
(
    echo nsComment = "Open Server Panel Generated Certificate"
    echo basicConstraints = CA:false
    echo subjectKeyIdentifier = hash
    echo authorityKeyIdentifier = keyid,issuer
    echo keyUsage = nonRepudiation, digitalSignature, keyEncipherment
    echo.
    echo subjectAltName = @alt_names
    echo [alt_names]
    echo DNS.1 = %DOM%
    echo DNS.2 = www.%DOM%
) > %config_txt%

mkdir %DOM_KEY%

set OSAPACHE_DIR=%~dp0..\..\..\modules\http\%APACHE_VER%
set OPENSSL_CONF=%OSAPACHE_DIR%\conf\openssl.cnf

I'm not very familiar with certificates and I don't have a lot of time for this rn so I need help.
