Dear,

I am failing to open Jupyterlab of a dataproc cluster GCP with an error of 

This page isn’t working right now.

europe-west1.dataproc.cloud.google.com can't currently handle this request.

HTTP ERROR 502

Help how can I overcome this; I don't have recent back of the code there.

Thank you.

When you encounter this error, it typically means that there's an issue with the server or service you're trying to access. It could be due to various reasons such as server maintenance, misconfiguration, network problems, or temporary service disruptions.

An HTTP error 502 typically indicates that the server (in this case, europe-west1.dataproc.cloud.google.com) received an invalid response from an upstream server while attempting to fulfill the request.

Here are a few steps you can take to troubleshoot this issue:

• Ensure that the Google Cloud Dataproc service is functioning properly. You can check the status of Google Cloud services on the Google Cloud Status Dashboard.
• Verify the health of your Dataproc cluster. If your cluster is unhealthy or undergoing maintenance, it might cause connectivity issues. You can check the status of your cluster in the Google Cloud Console.
• Ensure that the necessary firewall rules are configured to allow traffic to and from your Dataproc cluster. This includes both inbound and outbound rules. You may need to adjust firewall settings if you've made recent changes.

Hi , I'm facing the same issue, I always open the gcp in incognito and when using the Jupyter lab in dataproc, sometimes it is opening fine, but for few times  facing this 502 error.

The status page I check: https://status.cloud.google.com/

Wondering if there are any other ways to troubleshoot this error.

Thanks,
