Hello, does the firewall of the server have relevant ports open?
ufw allow 7800/tcp
iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 7800 -j ACCEPT
firewall-cmd --permanent --zone=public --add-port=7800/tcp > /dev/null 2>&1
Is there an error when restarting the panel now:
/etc/init.d/bt restart
