"PlotlyRequestError: No Message"

I have a free plotly account that I’ve been using for over a year to make charts. Everything was working perfectly till last Friday. I ran the code on Monday morning and I keep getting “PlotlyRequestError: No Message” error message and my charts aren’t generating.

I checked my credentials and the API key, everything’s the same.
The following is the exact error I keep getting in my console

File “C:\Users\xxz\Anaconda3\lib\site-packages\chart_studio\api\v2\utils.py”, line 179, in request
raise exceptions.PlotlyRequestError(message, status_code, content)

PlotlyRequestError: No message

Please let me know how to debug it.
