Custom app create using Connect not working

Question

Hello,

i created a hello world app and tunneled it to my site, the publish seems to work fine but when i access the app, it is not working.  It says

"Something's gone wrong, Our team has been notified. If the problem persists, please contact atlassian Support. Reload Page

The app is merely a hello world app, it has not customization at all, and yet it wouldnt work. Can you please me out here?

thanks

@Mike Most probably it is due to ngrok warning page in the addon's iframe. Even after clicking on `Visit Site` button in the ngrok warning page, sometimes, it doesn't go away from iframe. You may ensure this issue by inspecting the addon's iframe content.

I also faced the similar issue, so I thought to write an article around this issue. I hope this will be helpful:

There's nothing we can really tell you here, you need to put some debugging code into the app to have it explain where it is failing.
