Could you provide more details: browser name/version and OS?

To quick fix: edit /public/events.js line 14
socket = new WebSocket('ws://' + location.hostname + ':' + (parseInt(location.port) + 1));
to
socket = new WebSocket('ws://' + location.hostname + ':' + 5001));

Check Windows firewall. Ensure that 5000 and 5001 ports is unblocked. Look at this tutor to get more details.

http://10.120.102.42/device a some strange request. It must be http://10.120.102.42:5000/device

Could you check via Firefox or Edge? It's look like that Chrome ignores location.port.
I also use Win7/Chrome but don't have any problem with connection.

[wruffin1]

Need Help - I have it installed on my server and it works fine using any browser on my server adding 127.0.0.1:5000 in my address field. When i try to access the application from a client browser it fails can't find /device and /diagram both have an error of 404

[little-brother]

Check ports again. On client machine run telnet 10.120.102.42 5000 and telnet 10.120.102.42 5001. If the port is closed, a warning will be displayed. Here more details.

[wruffin1]

Got it, that works great. How do you access the port from http when you have no access to the command prompt on the server ?

These commands only check the ports, and do not access it.
From mobile devices, you can check open ports using special programs.
