Are you using Binary encoding and not Binary encoding with Variable Length Strings?

With binary encoding the size of messages are fixed and you can use the sizeof operator in the C++ language to check the structure sizes.


There are so many fundamental problems with this question:

Is it possible the server really sent 388 bytes for this message?

It should not even be asked. One problem is, there is no way for us to validate that your conclusion is correct. That is essentially advanced programming help. Which we do not provide. The second problem is that looking at this question in isolation, the server can be sending more data because there are other messages sent at the same time.

The reason it should not be asked is because you should already know that there is no way we can provide any type of proper answer.

. Furthermore, when encryption is enabled the client crashes after it is unable to decrypt the server response.
This indicates a problem in your code. This should not happen. Furthermore, what is the purpose of telling us this.
