*Question*

Connection timed out when visiting Flink website.

I think the reason is that too many history tasks in short time  leads to Flink service response slowly. 

!image-2021-09-12-09-37-31-177.png!

As the blow picture, there are 11091 history tasks to show.

*Solution*
 # The simple way is that adding one config to limit the number of history task in web ui;
 # add paging turning function to limit the number of history task in one response.

 

If you agree with me , i am pleasure to create a pull request.
