Hello everyone,
I tried to make my database backup as usual, but in this time I had the message:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request

Reason: Error reading from remote server

I repeat tentative many times but cannot make backup,
Is there someone who can help me,
I’m using Odoo 11

Thanks in advance
