Apache Web Server port 433 and Tomcat port 8080, redirect not working

My Apache webserver runs on port 433 with https protocol. I wish to run Tomcat on port 8080 because there is no need for additional encryption, Tomcat is on the same machine, so I don't need port 8433. But when I forward traffic from 433 to 8080 via iptables but I got an error: This site can’t provide a secure connection

ERR_SSL_PROTOCOL_ERROR

What configurations do I need in tomcat server.xml and apache.conf to make this work?

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443" />
    
    <!-- A "Connector" using the shared thread pool-->
    
    <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
<!-- I've tried this before when I thought I need an SSL for Tomcat. I think it's irrelevant now -->
    <Connector port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol"
               maxThreads="150" SSLEnabled="true" >
        <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
        <SSLHostConfig>
            <Certificate certificateKeyFile="conf/localhost-rsa-key.pem"
                         certificateFile="conf/localhost-rsa-cert.pem"
                         certificateChainFile="conf/localhost-rsa-chain.pem"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>

in httpd.conf

<VirtualHost *:80>
     ServerAdmin root@localhost
     DocumentRoot "/var/www/html"
     DirectoryIndex index.html
     ServerName mydomain.zone
     ErrorLog "/var/log/httpd/mydomain.zone.error_log"
     CustomLog "/var/log/httpd/mydomain.zone.access_log" common
RewriteEngine on
RewriteCond %{SERVER_NAME} =mydomain.zone
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>
Include /etc/httpd/conf/httpd-le-ssl.conf

EDIT: I have tried, as suggested, with ProxyPass "/" "http://mydomain.zone:8080/" and ProxyPassReverse "/" "http://mydomain.zone:8080/". Still the same issue.

I wondered if there was any iptables rule that I implemented before, but it doesn't seem so. These are current active iptables rules:
