Hi Carlo, I get the same error. Tried different kernel settings, but no success. Now I try to restart the Studio. Update: I can’t restart the Studio, I always get his message: AWS account deactivated at 2023-08-25T06:53:17-07:00 ---

I found out you can fill our a form to initiate a Reactivation of your AWS account. Today I was able to restart AWS, select the right VM and finish Lab 2. I think I found this Form in the FAQ section of the course here on the deeplerning.ai website. ---

Hi Reimelt. You should be able to access the lab now. Thank you! ---

Thank you for the replies. Still unable to continue with this Lab. Today the Kernel is not starting (“Starting notebook kernel…” status forever). ---

Hi Carlo. That might be because you chose a different instance type from the one expected by the lab. Please see that you’re selecting the same one as shown in the screenshot in the notebook. It’s usually `ml.m5.2xlarge` for this course, but please double-check in the screenshot. In case you have trouble getting into the lab because of too many retries, please fill out [this form](https://forms.gle/pELSiqxCVevBW3uP9), as also mentioned above. Just take note that for retries, it will take around 20 minutes before the AWS button turns green. Hope this helps! ---

Thank you for the solution, the issue is resolved and I was able to go through the lab.
