When experiencing difficulties, the first step is to increase the verbosity of the logs, by setting the LogLevel to 'debug' in your virtual host configuration file:

<VirtualHost *:80>
       LogLevel debug

Then follow the logs:

tail -f /var/log/apache2/error.log


Example log:

[Sat Jun 17 06:34:21.248253 2017] [autoindex:error] [pid 31089] AH01276: Cannot serve directory /var/www/http/: No matching DirectoryIndex (my_script.fcgi) found, and server-generated directory index forbidden by Options directive

Here my_script.fcgi was not found. Maybe you forgot to tell Apache where to find your script. Use the ScriptAliasMatch and AddHandler directives:

<VirtualHost *:80>
  ScriptAliasMatch ^/my_script.fcgi(.*)$ /var/www/cgi-bin/my_script.fcgi$1
  AddHandler fastcgi-script /var/www/cgi-bin/my_script.fcgi

Request exceeded the limit of 10 internal redirects

Example log:

[Wed Jun 21 04:26:29.952753 2017] [core:error] [pid 28481]  AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
[Wed Jun 21 04:26:29.952762 2017] [core:debug] [pid 28481] core.c(3761):  AH00121: r->uri = /my_script.fcgi/my_script.fcgi/my_script.fcgi/my_script.fcgi/my_script.fcgi/home

The above may be found in conjunction to an .htaccess directive like this:

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ my_script.fcgi/$1 [L,QSA]

The solution is the same as in the previous problem. A ScriptAliasMatch directive for my_script.fcgi is probaly missing in the virtuahost configuration.
