Installing: 502 proxy error

[DanielaLoureiro]

Hello everyone, I´m having a problem installing Coppermine gallery. I succesfully filled in the information about my MYSQL database, but when I tried to move to step 7, I got this error message:

502 Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /cpg15x/install.php.

Reason: Error reading from remote server

Could anyone help me to solve it? Thanks in advance!

Please try to use the classic installer.
