Connection freeze after a while

Hi Dear Streamrs

I am trying to fetch a large amount of data from about 9 months ago. I developed an app that subscribes to a stream with resent option. On the first try, I used a wide timeframe for the resent option (from: 9 months ago timestamp, to: now) but it freezes after a while and it doesn't receive any message or throw an exception. So on the second try, I used a loop to subscribe on a narrow timeframe (an hour), after that It fetches all the messages in this timeframe I will unsubscribe this timeframe and will subscribe to the next timeframe. But in this scenario, it freezes too. I tried these on different networks and different devices, the result is the same as each other. It is not happening at a specific time or after some amount of messages, it is completely random. How can I help you to investigate this issue?
