Does your IP address begin with "192.168.1." by any chance?

When you say "different computer", are you on another computer within the same
LAN (i.e., on the same side of a firewall) or on a different subnet (i.e., on
the other side of a firewall)?

IP addresses do not uniquely or reliably identify a client.
Conversely, a client can have more than one IP address.
If there is a firewall involved, the IP address as seen from outside the
firewall is different from that seen inside.
Whether you can even reach your server from outside the firewall is a matter
of whether the firewall lets connection attempts for port 8080 reach your server.

you can try to request the url from you local computer :
http://Ip address : 8080/web_context/alias_name
If success,ping from another computer to your machine:
ping ip address.
