Thanks for your response Thanks for trying to create a crash with your code. I updated the card with how I created a crash and thought it was important to you. We will try to improve the App and remove the crashing. Kobi ---

@meridork Thank you for your understanding and cooperation. However, I’ve come across a topic that appears to be related to the issue you’ve been experiencing. It seems to be a problem associated with **Flutter** , as discussed here: [Frequent bad file descriptor errors on iOS #197](https://github.com/dart-lang/http/issues/197). You may need to do further research to address the remaining errors, as they could potentially originate from Flutter itself. I hope this information is helpful! Apart from this, if you have any questions or encounter any issues with our product, please don’t hesitate to get in touch 🙏 ---

Thanks Can you please describe the process that using following address that in the exception error? `SocketException: Bad file descriptor (OS Error: Bad file descriptor, errno = 9), address = ssq.eu.amity.co, port = 50391` ---

It may not be related to the address. We still recommend conducting additional research around that topic. Until you have the debugging tool and can provide logs from the iOS side, we won’t be able to provide further assistance 🙏 🙂 ---
