Can we import opportunities using impor wizard? I think only Account, Contact , lead and solutions can be imported. The trailhead article on Data import says 'Opportunities can be imported' . Hence the question

I am not able to access the help and training link from our production systems.
It keeps redirecting to the message 'There was a problem with your authentication attempt. Please try again. If you continue to encounter problems, contact your administrator.' I have tried with all browsers, reset cookies etc.. with no luck. Is anyone else facing the same issue. I am not able to raise a support case with salesforce also .

I noticed also that whenever I am trying to access success.salesforce community it says too many redirects.

Anyone facing similar problems?
