Replace global scope with CoroutineScope for socket operations (#3454)

Replaced the use of global scope with CoroutineScope(Dispatchers.IO) in the socket operation function. This change improves coroutine management and ensures proper use of dispatchers for background tasks. The code now properly handles retries with exponential backoff and logs attempts and errors.
