Failed in creating scenario

[xie-haonan]

Describe the bug

When creating a scenario, here follows the detailed information:

urllib3.exceptions.SSLError: TLS/SSL connection has been closed (EOF) (_ssl.c:1131)

The above exception was the direct cause of the following exception:

urllib3.exceptions.ProxyError: ('Unable to connect to proxy', SSLError(SSLZeroReturnError(6, 'TLS/SSL connection has been closed (EOF) (_ssl.c:1131)')))

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

Expected behaviour
This is my first time with CEA and I want to have a successful utilization.

Based on the error message, there seems to be some issue with an external library connecting to the api fetching the building geometries (could be some issues with the internet connecting to it). I am wondering if you are able to access this endpoint from your browser: https://overpass-api.de/api/status .

If you see a response on the browser, could you try running using CEA again and let us know if it still works.

Thank and I can access this endpoint.

The scenario creating doesn't work.
