Maybe this workaround can help you? It can be a firewall issue.
Customer are reporting an error "unable to load scrip" when testing the Mobile native app on the mobile devices using the "Make It Native" app.
Also, they can’t see the URL in the mobile browser.
If the firewall settings aren’t correctly configured or the computer and mobile device aren’t in the same network, Studio Pro and the "Make It Native" app can't communicate to each other.
How to reproduce the issue
Build a Native App and have your mobile phone in a different network.
It supposes to automatically launch your test app on your mobile device. But the client gets the "unable to load scrip" error in the mobile screen.
Client needs to verify the following steps.
Open the Firewall & network protection setting in Windows, go to the advanced settings, select the Inbound Rules and scroll to the Node.js entries. They should all have a green check mark in front of them.
If not, double-click the entry, select Allow the connection and click Apply.
With the firewall settings correctly configured and both computer and mobile device in the same network. The client will see his app on the ”Make it Native” app
If above both steps don't resolve the issue, check if the network is configured as "Public" on the computer, and if so, convert it to "Private". Re-check the firewall settings, if not already allowed, and allow access to private networks too.
Root cause: Studio Pro can’t communicate with the mobile device. With that Make It Native App can’t get the files from the modeler.
Thanks you all,…
I solved the problem.
My company changed my pc, with a newer one by applying new policies for which the PC, by default, was not visible except to members of the domain. The mobile is not under domain. By enabling the visibility and restarting the pc everything started to work.
