I’m having issues with the web API as well - even when using the app from a Thunkable tutorial (Countries Info App).
Whether I use Preview online or Live, the app crashes whenever I enter a country name and press the search button. In Preview, the screen just goes blank. In the Live app, it just returns “Something has gone wrong. Check your blocks and reset this page.” If I output the response, status and error data to a label, I get a blank response, a blank status and an error that says “The website or service provider you are trying to reach does not support HTTPS requests.”
Here’s a link to the Countries app that originally came from the YouTube tutorial. I’ve detatched the bulk of the code on the second screen, added a “debug” label, and written the API responses to that label so you can see the error. https://x.thunkable.com/copy/3cac341ddea2ac628d6d0c037fce60d3.
I have students trying to build this app, and they’re having trouble. This app used to work fine for me, so I’m wondering if something changed recently with Thunkable. Note that I can’t get the Thunkable weather app to work anymore either - same results as the Countries app.
