Snowflake Query/task gets canceled cause of timelimit

I set up a code, to load Data from Google Analytics from a raw GA table to an adapted table, that offers more insights. Somehow the Task is not running inside the defined time limit of 3600 seconds. So the task is getting canceled and no data is loaded.

"Statement reached its statement or warehouse timeout of 3,600 second(s) and was canceled."

Then I load it in a manual way by using a fixed Clause: WHERE gae."DAY"='2020-03-31' instead of WHERE gae."DAY">=CuRRENT_DATE-1. It takes still much time but works in the end.

How can I make this query faster? Or anyway, solve my problem.
