AppOfflineError: Constantly happening now

[mr_alex]

For like the last two days now I’m getting this error all the time. It happens during regular page load events or linking from one page to another. It’s like the session expires and I have to reload the whole app again. Then it works for a couple of pages and then it’s the infinite circle spinning until the “app is offline” comes up. Doesn’t happen in the dev environment. I’m currently using a custom domain, but it was more stable just a few days ago. Nothing in the app logs. This is really frustrating. Anyone else?

Search AppOfflineError in the forum, if you haven’t already, to find the results of others’ troubleshooting this in the past. it could be your internet connection or a browser extension interfering, for instance, though it’s hard to see how those explanations could fit with “Doesn’t happen in the dev environment.”

See also these ideas for more gracefully handling this error:

AppOfflineError Connection to server failed

You can add something like this to your startup code (assuming you haven’t already set up custom error handling, in which case you’d need to modify that code): def error_handler(err): if isinstance(err, anvil.server.AppOfflineError): handle_server_connection_error(err) else: raise err def handle_server_connection_error(err): Notification("Server connection error. If something is not working as expected, please refresh the page.", style="warning", timeout=5)…

Generic Offline Mode Handler Logic

Nothing spectacular, but I thought I’d share it anyway. Basically a higher order function that you can wrap arbitrary functions in so offline mode cases are handled on the form side. Plug your functions to handle in here. def try_action(self, function_to_try): try: function_to_try() except anvil.server.AppOfflineError: alert("No network connection. Check your connection and try again later!") For example here’s an event handler for a click event: def button_save_to_d…
