View source for ProxCP Web and ProxCP Daemon Error Troubleshooting

== ProxCP Web ==

* '''ERROR:''' Blank/white page when adding a new Proxmox node (ADMIN > Settings > Manage Nodes)
** PHP 7.2 mcrypt might not be installed. To install it on cPanel, issue the following commands in SSH:
<code>yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm<br>
yum install libmcrypt<br>
yum install libmcrypt-devel<br>
/opt/cpanel/ea-php72/root/usr/bin/pecl install channel://pecl.php.net/mcrypt-1.0.1<br></code>
** Restart httpd and PHP-FPM (if enabled)

* '''ERROR:''' "license check failed error: install is only allowed on a real working domain"
** ProxCP Web can only be installed on a domain name, not an IP address. ProxCP checks the installation location based on the actual URL. The URL must be a domain or sub-domain, not an IP address.

* '''ERROR:''' redirected back to a form with no displayed or logged errors
** The form's CSRF prevention token check may have failed. In your php.ini file, ensure session.save_path has a valid directory value and your web server user (i.e. www-data, apache, etc.) has permissions to it.

== ProxCP Daemon ==

* '''ERROR:''' NPM error when installing forever on a cPanel server
<code>npm config set strict-ssl false</code>
* '''ERROR:''' EADDRINUSE
** You have another process already using the same port as the ProxCP Daemon (port 8000 by default). Be sure you are only running 1 instance of the Daemon and no other program is using the same port.
