Hi All,
User is using winform application with SQL express. Application is working fine and suddenly he was seeing exception window with data extraction error.
Exception details are :Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ; SQL exception number is -2.
Within fraction of seconds if user hits F5 application is working without any issues. I don't see any help online except that exception number -2 means firewall is blocking the connection.
I wanted to either reproduce the issue on my end or wanted to know exact reason for the error. Appreciate your response.
Thanks
