You can start a new preview session for your page from the Backendless Console. Sessions are implemented to enable bypass of the billing for the file requests and as a result, they are timed.
The Preview link is intended to be used only by the developer. You should not share the preview link with the users of your app. Instead, you can publish your UI Container and share the app link with the users.
Maybe there is a misunderstanding. I have not shared the developer link with anybody else. I have published the UI container to my domain as always. When a user access the domain the above posted message appears.
I mentioned a similar topic a couple of weeks ago to support that my developer preview shows my production domain and not my backendless sub-domain anymore. But I received the answer that this should be ok. Maybe this causes the problem.
Could you please take a look into this. My App Id is 66C2DBD4-189A-7377-FF95-915D98235700
When I open your custom domain in a browser (or the xxxxx.backendless.app domain assigned to your app), the application opens and is functional (I’ll be happy to share a screen recording if you’d like).
Could you try opening your domain in a different browser and see if it works? Additionally, try the Incognito mode in Chrome. Finally, try clearing your browser cache and see if it fixes the problem.
