I'm trying to create a debian image for openstack from a file.
on the graphical interface it still remains waiting.
On the command line: I receive the message:

HttpException: 502: Server Error for url: http://192.168.11.40/image/v2/images/1bb75b80-f6d2-4a26-a941-a52b03e48455/file, : 502 Bad Gateway: Bad Gateway: The proxy server received an invalid: response from an upstream server.: Apache/2.4.52 (Ubuntu) Server at 192.168.11.40 Port 80

Merci
