Error -337 on Webos4

Lastly I figured that my app can’t be open and an error of -337 is appeared:

It occur immediately after launching the app, but there is Internet on other applications, and the site that the app launch can be open via the browser on the TV (so I don’t understand why it is saying that there is network issue)
I also try with the webOS IDE to run app (even with window.location.replace(“”); and it still has the same error)
I have tried it on WebOS 3.5 and it work,
Webos 4.4.0-12 DOESN’T work

I also send it in 1:1 Inquiry but maybe here there will be faster respond if something else encounter similar case


Can you please share with us a sample app for testing at
