401 unauthorized error on variationroot.aspx page RRS feed

  • Question

  • Hi,

    When I try to open home page of my sharepoint site, I get '401 UNAUTHORIZED' error on variationroot.aspx page. This error disappears when I refresh page 2 or 3 times and home page opens successfully.

    Can anyone please tell me the possible reason behind this? What should I do to overcome this issue?
