socket.send(), OSError(), TimeoutError(), Connection lost/reset

If you get any of these errors chances are you ended up with a slow or inconsistent network connection. Another reason could be because you are blocking the event loop for too long.

You can consider the following:

• Use Hydrogram asynchronously in its intended way.

• Use shorter non-asynchronous processing loops.

• Use asyncio.sleep() instead of time.sleep().

• Use a stable network connection.
