Stucked like Evergreen with proxy on MyBinder

From Python kernel in Jupyterlab cannot connect to proxy.

With code:

import requests
proxy = {“http” : ‘’}
r = requests.get(‘’, proxies=proxy, )

I got this error:
[ProxyError: HTTPConnectionPool(host=‘’, port=80): Max retries exceeded with url (Caused by ProxyError(‘Cannot connect to proxy.’, NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x7fae4de90250>: Failed to establish a new connection: [Errno 110] Connection timed out’

It’s a working proxy, how to connect from Jupyter?

It looks like your proxy isn’t publicly accessible.

Thanks, ship has sailed!

It was false alarm, caused by my proxy, not MyBinder.
(e.g. ran)
