You start out with a bold claim (cancellation can lose data). I don't think that's true.

Also, you can significantly simplify your code and also allow for concurrent connections at the same time. At the root of this, I detect a C-coding style, so allow me to show C++20 style:

#include 
#include 
#include 
namespace asio = boost::asio;
using namespace std::chronoliterals;
using asio::ip::tcp;
using boost::system::errorcode;
asio::awaitable Session(tcp::socket s) try {
    errorcode ec;
    auto       timed = cancelafter(5s, asio::redirecterror(ec));
    for (std::array data; !ec;) {
        auto nread = coawait asyncread(s, asio::buffer(data), timed);
        if (ec == asio::error::operationaborted) {
            std::cout
