App working on Android 8 and older, error in android 9

[Android Central Question]

I have an App which is working on Android 8 and older version of Android smoothly,but in android 9, it gives an error of “Connection Timeout”. What could be the problem?

Have you emailed the developer?

Welcome to Android Central! It sounds like the developer didn't optimize the app to run on Pie. When was the last time it was updated? If it was more than a year ago, then the developer might have abandoned the app. Do as belodion suggested and try to contact the developer.
