UAPI access to cPanel is not available about letsencrypt

[imbrish]

This error is displayed when the uapi command is not available in the environment where the script executes.
In principle uapi token is not required, because the script should be running on the same machine.

I'd try checking with your hosting if they support uapi and if so how it could be enabled and/or used. If you get uapi to work manually, but the script is still unable to access it, you may probably patch this part of code:

letsencrypt/bin/letsencrypt

Lines 80 to 85 in f3bb197

	if (! $uapi = exec('which uapi 2>/dev/null')) {
	$climate->to('error')->error('UAPI access to cPanel is not available!');
	exit(EX_UAPI_NOT_FOUND);
	}
	define('UAPI_BINARY', $uapi);
