Sorry I dont know how to find out what server and gameId but presumably there is a way by looking at the time of this post vs my last game (ie. around 10:20am).
After buying the last province and ending my turn the game didnt end or goto the normal summary of scoring page.
I had played a crypt and horn of plenty (to get one of the provinces) just before the game ended if that is helpful.
eventually i refreshed on the browser and it brought me back to the main login screen
