I just did a new installation with iRedMail 1.3.2 and am having an issue with RoundCube.  I can log into the RoundCube application fine, but once logged in, I get errors that popup on the screen stating the following:

Server Error: LIST: Internal error occurred.  Refer to the server log for more information.

I installed iRedMail with the downloadable installer and am running Nginx 1.14, PHP 7.4, and MariaDB on an AWS EC2 instance running Ubuntu 18.04.

The error I see in the nginx error.log (tail /var/log/nginx/error.log) is:

2020/11/21 02:38:55 [error] 1002#1002: *5 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 127.0.0.1, server: _, request: "GET /status?full&json HTTP/1.1", upstream: "fastcgi://unix:/run/php/php-fpm.sock:", host: "127.0.0.1"

Here is my nginx.conf file:

ubuntu@mail:/etc/nginx$ cat nginx.conf
user www-data;
worker_processes 1;
pid /var/run/nginx.pid;

events {
    worker_connections 1024;
}

http {
    include /etc/nginx/conf-enabled/*.conf;
    include /etc/nginx/sites-enabled/*.conf;
}

And the roundcube.tmpl file:

ubuntu@mail:/etc/nginx/templates$ cat roundcube.tmpl
#
# Running Roundcube as a subfolder on an existing virtual host
#
# Block access to default directories and files under these directories
location ~ ^/mail/(bin|config|installer|logs|SQL|temp|vendor)($|/.*) { deny all; }

# Block access to default files under top-directory and files start with same name.
location ~ ^/mail/(CHANGELOG|composer.json|INSTALL|jsdeps.json|LICENSE|README|UPGRADING)($|.*) { deny all; }

# Block plugin config files and sample config files.
location ~ ^/mail/plugins/.*/config.inc.php.* { deny all; }

# Block access to plugin data
location ~ ^/mail/plugins/enigma/home($|/.*) { deny all; }

# Redirect URI `/mail` to `/mail/`.
location = /mail {
    return 301 /mail/;
}

location ~ ^/mail/(.*\.php)$ {
    include /etc/nginx/templates/hsts.tmpl;
    include /etc/nginx/templates/fastcgi_php.tmpl;
    fastcgi_param SCRIPT_FILENAME /opt/www/roundcubemail/$1;
}

location ~ ^/mail/(.*) {
    alias /opt/www/roundcubemail/$1;
    index index.php;
}

And the fastcgi_php.tmpl file:

ubuntu@mail:/etc/nginx/templates$ cat fastcgi_php.tmpl
#
# Template used to handle PHP fastcgi applications
#
# You still need to define `SCRIPT_FILENAME` for your PHP application, and
# probably `fastcgi_index` if your application use different index file.
#
include fastcgi_params;

# Directory index file
fastcgi_index index.php;

# Handle PHP files with upstream handler
fastcgi_pass php_workers;

# Fix the HTTPROXY issue.
# Reference: https://httpoxy.org/
fastcgi_param HTTP_PROXY '';

And lastly, the fastcgi_params file:

ubuntu@mail:/etc/nginx$ cat fastcgi_params

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

Anyone know what is wrong with my configuration?
