I can't read the contents of my connection file on the operating system win2019. What's the reason? With the guidance of that expert, thank you



As I can see from the logs the host, user and database are empty, so you are connecting to nowhere. make sure your .ini file is located in right directory.

probably UAC changed the directory of terminal. for testing you may set database credentials directly in EA and make sure of successful connection.
