Stucked like Evergreen with proxy on MyBinder

From Python kernel in Jupyterlab cannot connect to proxy.

With code:

import requests
proxy = {“http” : ‘http://162.14.18.11:80’}
r = requests.get(‘http://ipinfo.io/ip’, proxies=proxy, )
print(r.status_code)
print(r.text)

I got this error:
[ProxyError: HTTPConnectionPool(host=‘162.14.18.11’, 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 http://162.14.18.11/ isn’t publicly accessible.

Thanks, ship has sailed!

It was false alarm, caused by my proxy, not MyBinder.
(e.g. http://142.93.214.51:80 ran)
