There is now an indicator that tells you if the current auth configuration is working every time you start the program. If the indicator says UP and you're having issues scraping, then it's an issue on your end.
The config file actually has a use now. You can now specify a download location and a max file size. With the max file size, enter the number in bytes. Entering something like "1 GB" will not work, you'll have to convert 1 GB to bytes. If you don't want a limit, leave it blank or set it to 0.
