Have you encountered any fatal problems when using this library?

During the development phase of the Windows platform, there is a business middleware of my own. Both before_handle and end_handle have their own codes. The client sends an http post request and passes json data. The whole business is normal and can request and respond correctly. However, during the operation, the webapi requested may be in the fin_wait_2 connection state with the server. In this case, subsequent webapi requests and responses cannot be made. I have encountered this many times. This cannot be used as a web server. Have you not encountered this? I wonder if the crowcpp version has this similar bug.
