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?
