When I go through this link I'm not able to login with chat see the screenshot and I tried hard refresh also. Right now I have 976 rep.
The link you followed is a search link, so it shows you the parts of chat transcript where the term was found. If you dismiss the notification bar covering the top of the screen, you should be able to see the search boxes followed by "in room Tavern on the Meta". The room name is a link to the room itself.
