I get the following error while trying to connect to the SharePoint environment. It is no problem to open up the site using IE. I have also tried it specific user accounts, but without any luck.

Thank you for your detailed post in the our forums. Can you provide some
details about the SharePoint instance that you are trying to connect to:

1) Is it located in a cloud?
2) What kind of authentication are you using? (Proxy, Domain, FBA, SSL, SSO, Kerberos, etc)?

If you are connecting to an instance located in a cloud, please refer to this
