DNS lookup failure for:

Question

I installed my server with virtualmin, and I am using apache with php fpm. When I try to open my website I have this error :

Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /index.php.

Reason: DNS lookup failure for:

After the "for:" it is empty

Here is my apache2 conf file for this site :

The format of your SetHandler directive to pass to a UNIX domain socket is wrong.

It should read as shown in the documentation:

SetHandler "proxy:unix:/var/run/154262472926263.sock|fcgi://localhost/"

Keep in mind you have placed it in two places in your configuration.

Also keep in mind that you may have other configuration problems which are not obvious here.
