You have to create a debug log. Go to Settings-Advanced Settings- search for debug and enable log debug.
Restart JDownloader and try to remove/add the Account again.
Then create new log please

I hope this is ok.

Where I should add the whitelist?

Edit:

I understand. I should add whitelist in datafile site. Thanks for support.
