Proxy error in mail.gnome.org

[Daniel Mustieles García <daniel mustieles gmail com>]

Hi sysadmins!

I'm getting the following error when trying to access the admin page of a mailing list [1]:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /mailman/admindb/gnome-es-list.

Reason: Error reading from remote server

Could you please take a look into it?

Thanks in advance for your help!
