I set my login and password for a protected site in IDM "Options→Sites Logins" dialog but it does not work. What should I do?
Please check that you selected appropriate protocol for your URL in "Options→Sites Logins" dialog.
Please also note that sometimes downloads may have different URL than the basic server. For example, you use the site "https://www.mysite.com" and downloads come from "https://members.mysite.com". You may try to use wildcards in the URL like "*.mysite.com".
