1. Check your login / password from the OPR.
2. Check the connection to the OPR website through a web browser. Administration OPR periodically asks users to read and Accept terms and conditions of website (you need to put a checkbox for all new accounts). This leads to the problem of connecting software.
3. Add OpenTool to the exception list ("white list") of your firewall / firewall. A simple disable these programs may not yield results, because OpenTool often remains without access to the Internet.
Also remember that you just might have a broken internet connection or the OPR server works with lags. Just try to connect later.
