Hi @rodman0803,

That’s normal behavior. You can’t have an SSL certificate on an IP address. You can try and Add Exception for this website/IP address on your browser and this should be fine.

If I’ve misunderstood the issue and you are not able to connect due to another reason, it’s possible your firewall is blocking the connection to port 10000. On an Ubuntu server with UFW firewall, we execute

sudo ufw allow 10000/tcp

Similarly, to open port 10000 in iptables, we use

iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 10000 -j ACCEPT
