Hello, your port 7800 is not open, please check whether the firewall is open? Is aapanel running?
Try to open port 7800, and the security group of the server provider should also open port 7800
firewall-cmd --permanent --zone=public --add-port=7800/tcp >/dev/null 2>&1
firewall-cmd --list-all
/sbin/ufw allow 7800/tcp
/sbin/ufw status
Try restarting aapanel:
/etc/init.d/bt restart
