Electrum connection on mobile device constatly breaks

On Apple mobile devices (all iPhones and iPads, iOS 14) Electrum connection gets broken after some small time even if app is not in the background, This does not happen on iOS simulator though. Unfortunately I was not yet able to acquire debug/trace logs of what's going wrong (iOS device does not print debug info in rust code and I am still figuring how to do that), So I just see that ElectrumClient starts returning an error on all method calls and not yet able to trace which specific error is that. Will keep updated, but opening an issue in case if you know something about this problem already.

I assume that this is caused by iOS closing TCP connection after certain period of time (even for foreground apps).
