In Mathematica 11.3 on Mac and Windows.

Once I've set up the connection with gridMathemtaica's remote kernels. Then I close those machines/kernels and restart my Mathematica.

When I click the Lightweight Grid Button, my frontend will be stuck, and after a few seconds, $Abort shows, I can do nothing but force quit Mathematica.

After check the log, I found the problem is because of the request's timeout of some configured remote kernels. So I can solve this problem by delete my settings in the config file. But this is not convenient.

There must be something wrong with Mathematica relate(or similar) with this Dynamic problem which is a nightmare an old dynamic problem
