When opening JOScan there is a long pause that will then error out. When the error message is present clicking ignore the app opens and work just fine.
This is an issue with the client talking to SQL and timing out on the HandShake. More of a network issue then an app Issue.
Add a time out in the connection string to SQL:
It should be added as Password=P@$$w0rd;Connect Timeout=300"
It needs be inserted inside the Quote for the Connection String.
