Week3 - Notebook Kernel load error

Please help, getting the following error multiple times while loading W3 assignment-
Getting the following error in sagemaker:
Starting notebook kernel…
Had error starting kernel 2 times.

Responded with error: Connection timeout between notebook and kernel.

Where you able to solve this ? I am getting same error in Lab2.

I had the same issue, when switching from safari to Chrome, the kernel got started quick.
