Sounds like you need to open port 8088 to public traffic on your cloud machine.
On remote server:
- Click start and search for “Windows Firewall with Advanced Security”
- Select “Inbound Rules” in the left pane
- Select “New Rule” in the right pane. A wizard should pop up
- Select “Port” and next
- On the next screen, make sure TCP is selected and 8088 is entered into the “Specific local ports” box and next
- Select “Allow the connection” and next
- Leave all boxes check and next
- Give it a name like “Ignition Inbound” and click finish
You should now be able to visit http://xxx.xxx.xxx:8088 and access the gateway.
After this is done, you should see your rule in the Inbound Rules list. You can double click it to edit other properties including what IP ranges can access that port.
Hope this helps.
