We recently upgraded our c++ client using Embaracadero Tokyo 10.2 C++ Builder Update 1. The client is using our own web service which has not been upgraded and built using Borland/Codegear C++ Builder. We have tested and deployed the client. In production, under certain situations (mainly slower connections), we are getting this error message. Looks like this message is displayed when our backend/database operation crosses 30 seconds at which point we are supposed to see a time out message. Instead this error is shown. Not sure how to trouble shoot this issue. Is there a possibility of incorrect handling of error messages between the client and the web service. We never had this issue with our old client compiled using Codegear C++ Builder.
