In forum module, Drupal generates the feed url automatically, that is excellent. But the issue is, the feed url generated doesn't contain the facing slash (at the start of the url), because of this, the search crawler(bot) assumes the url as relative and leads to page not found.
Bug1: The default forum (General discussion forum) page url is '/forum/1' where '1' is taxonomy term id (which varies if you have some terms already before installing the forum module) and the feed url for that is 'taxonomy/term/1/feed' without the guiding slash at the front which leads to the confusion.
Bug2: When we navigate to the '/forum' page, the feed url still gets created and now it assigns '0' as term id ('taxonomy/term/0/feed') which is bug.
