Update for simple FTP Uploader Program

I have a custom application written in C++. The project was developed in Visual Studio 2017. The program needs three very small changes. The program is an FTP uploader that takes a file and uploads it automatically to my server. You type in the FTP server details, located the file, and hit upload. It also has a button called "Default" that automatically fills in server info for a test server. Here are the changes I need 1) Change the Default server details 2) The app doesn't remember my previous settings. In other words, if I type in [login to view URL] and exit the app, when I open the app again the field is blank. 3) The app fails to upload the file after about 60 minutes. I need detailed logging added to the app so that the app will tell us what the error is. This should take 30 minutes or less. Thanks
