You may encounter an Error 403 with Simple Hosting instances in the following event:
- No index page has been defined in the repertoire, which therefore causes the following error in Apache’s logs:
[Mon Nov 25 09:33:29.272185 2013] [autoindex:error] [pid 2502:tid 2981512099584] [client 2001:4b98:x:x:x] AH01276: Cannot serve directory /srv/data/web/vhosts/domain.example.com/htdocs/: No matching DirectoryIndex (index.php,index.html,index.htm) found, and server-generated directory index forbidden by Options directive
By default, the Apache web server delivers the page named
index.php at the root of the directory, as the homepage. Consequently, if you encounter this error, you need to rename the homepage of your website to be
index.php. If you do not want to modify the name of the file of your homepage, you can also add the directive
DirectoryIndex in a ``.htaccess` file located at the root location.
Failed to read from backend server¶
[Mon Aug 19 15:01:55.242179 2013] [:error] [pid 412:tid 2997121103616] (104)Connection reset by peer: [client 2001:4b98:x:x:x] FastCGI: failed to read from backend server
This error indicates that the Apache service did not get a response from the interpreter (PHP, node.js, Python, etc.) and so it was unable to deliver the requested page. When this error occurs, you should analyze the interpreter’s logs in order to search for the error that is at the origin of the problem. To find the corresponding logs, it is recommended that you get the information from the date and time in the logs.
