I am getting Internal server 500.

Please Help

I am currently unable to load the Jupyter Notebook. When I click on the "Open Tool" button for the Peer-Reviewed Assignment on week 5, it brings me to a page with "Please wait while we prepare to start your lab environment." and a loading circle. It loads for very long (might have been more than an hour) and does not come up with an error message. I have tried using different browsers, cleared my cookies, used incognito mode, and changed my internet connection. It still does not work. Please help. Thank you.

While I trying to retrieve data from database IBM Cloud using the below

query = "SELECT COUNT(FDID) FROM FARMPRICES"
sqlQuery(conn,query)

I am getting following error:

Error in odbcFetchRows(channel, max = max, buffsize = buffsize, nullstring = nullstring, : negative length vectors are not allowed
Traceback:

1. sqlQuery(conn, query)
2. sqlGetResults(channel, errors = errors, ...)
3. odbcFetchRows(channel, max = max, buffsize = buffsize, nullstring = nullstring, . believeNRows = believeNRows)

The instructions for Exercise 3 - Create new cells, do not seem to be valid anymore and need to be updated.
Step 2 states From the menu, click on Insert, then Insert Cell Above or Insert Cell Below. Which menu is being referred to? There does not seem to be a menu called Insert that is visible.
Step 3 states to use the keyboard shortcuts: [a] - Insert a Cell Above; [b] - Insert a Cell Below. Selecting a cell and pressing a or b does not seem to perform any action.

I can no longer access Courser JupyterLab: https://labs.cognitiveclass.ai/tools/jupyterlab/lab/tree/labs/DL0321EN/DL0321EN-2-1-Data-Preparation-py-v1.0.ipynb for the course https://www.coursera.org/learn/ai-deep-learning-capstone/home/welcome.
The error I receive is
"502 Bad Gateway
The server returned an invalid or incomplete response."

I keep getting the error (see attached) stating that my account is under deletion, and I have had this error for 3 months without any resolution.

I have tried contacting support, I have message 1 every month since the error first showed, and there has been absolutely no response. The service has been appalling, no one has acknowledge messages and my assignments have been overdue because of this. The service needs to be far better, support is not good enough at all.

please, can you help me?
