SageMaker Studio will not load

Hello. I ran into a similar problem. I think SageMaker Studio, since it's in preview, is not yet a super-stable platform. To resolve this issue I just kept trying to launch the sagemaker studio from the aws console ('open amazon sagemaker studio' button from within the amazon SageMaker > Amazon SageMaker Stuiod > d-***** men). I received the same error about ten times but eventually I was able to get through to see the notebook I had previously created.

Hope this helps!

I see the same issue. SM Studio was working on the evening of 1/6/2020. I shut down the Juypter Lab and haven't been able to access it since. I've tried accessing via the SSO dashboard, as well as an admin user via the AWS console.

CHROME returns:

This page isn’t working d-*********.studio.us-east-2.sagemaker.aws didn’t send any data.
ERR_EMPTY_RESPONSE

FIREFOX returns:

Secure Connection Failed
An error occurred during a connection to d-*********.studio.us-east-2.sagemaker.aws.
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

SAFARI returns:

Safari Can't Open the Page
Safari can't open the page "https://d-*******.studio.us-east-2.sagemaker.aws/jupyter/default" because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again.

I tried for a few hours last night and again this morning. The problem persists. Any suggestions or support with this would be greatly appreciated. Thanks.

Still having the same issue, trying about once a day since the original errors.

I have the same issue. I have shut it down last night and could not find a way to open it or restart the whole amazon sagemaker studio service.

I was able to fix this by completely deleting my Studio instance with the AWS CKI. Of course you'll use any ephemaral data. You can then start over from scratch. Here is the sequence of commands.

aws sagemaker delete-app --domain-id yourDomainID --user-profile-name yourProfileName --app-type KernelGateway --app-name base-python
aws sagemaker delete-app --domain-id yourDomainID --user-profile-name yourProfileName --app-type JupyterServer --app-name default
aws sagemaker delete-user-profile --domain-id yourDomainID --user-profile-name yourProfileName
aws sagemaker delete-domain --domain-id yourDomainID

I am facing a similar problem for one of my SageMaker users. The default app, which is the Jupyter server, keeps failing while trying to launch SageMaker studio. I am receiving the following message: "The JupyterServer app default encountered a problem and was stopped.". I click on the Restart button, but the message appears again. Does anyone know how can I solve this issue? Or do you recommend paying for AWS support?

Had the same issue and managed to fix it (and preserve my data).

1. In AWS console navigate to SageMaker Studio
2. In the users section at the top, open the user (user details page) that is experiencing this issue.
3. At the bottom of the page, delete all apps for this user. There will be the default app (which is jupyter server) and sometimes others like KernelGateway. DO NOT DELETE THE ACTUAL USER PROFILE.
4. When all apps for this user is deleted, go back to SageMaker Studio and click on the "Open Studio" link for that user.
5. It will take some time, but SageMaker Studio will reinitialize that Jupyter Notebook.

The notebook will open and you should have all your data as it was before.
