The the connection to the server was unsuccessful

I have a Native App that runs fine on iOS and most Android. On some Android I get:

Application Error
The the connection to the server was unsuccessful. (https://localhost/index.html)

when the app is starting.

Any ideas?

Thank you,
Warren

This is happening at runtime, right?

If so, it probably has nothing to do with VoltBuilder itself. Next step will be to see how you can reproduce it, so you can narrow in on the cause.
