OK - I add 2443 manualy to firewall:
<log>
firewall-cmd --permanent --add-port=2443/tcp --zone=public
firewall-cmd --reload
</log>
OK - httpd conf is still 443 instead of 2443, I change it manualy:
<log>
vi /etc/httpd/conf.d/ssl.conf
</log>
I see, that dissabling selinux is necessary - I do so:
<log>
vi /etc/sysconfig/selinux
reboot
</log>
it still not work - in the Browser:
<log>
Errorcode: SSL_ERROR_RX_RECORD_TOO_LONG
</log>
