Hi, I have an app on the AppStore, but a few times, I get reports from users that he gets -1003 "Could not find a server with the specified hostname" on a 4G network. I tested on my iphone app and the problem is normal.
Knowing that -1003 doesn't happen to all users, maybe there is some setting on the phone that is causing this? Or is there a way to help the user to fix it (reboot or Wifi)?
If anyone knows the problem please let me know, thanks.
Hi, I have an app that has been online for a long time, but a very small number of users will respond with "-1009, the internet connection appears to be offline" error, but most users are normal, which may indicate that it is a device problem. The user's network uses 4G, and the user indicates that it is normal to connect to other apps.
In my opinion, if my App uses URLSession to get this Error, other apps should also get it, and all apps cannot make network requests, but it is not.
Currently I always ask users to restart the network or use wifi, but this may not solve this problem. Maybe the device has other network settings that can cause this problem? (The user did not use the flight mode)
Anyone know any solutions or know this problem?
Since the release of iPhone 12, I have received reports from iPhone 12 users about the crash problem. Later, I discovered that this problem occurred not only in iPhone 12, but also in other models, but most users said “App Crash after updating iOS 14".
This problem does not occur to all users (approximately one in a thousand), but the user who reinstalls the app still crashes in the same place.
I have tried several methods (such as using different versions of xcode build App), but still not solved...
And all the people around me who use iPhone can’t reproduce this problem, which also makes testing difficult
Does anyone have any ideas? Or how should I solve it?
