Hi, @Nerogee, could you attach debug and exception log?

[Nerogee]

sorry @joni-jones , I already removed whole installation and those files are gone. I remembered at that time is when such error happened, there is no any exception. But from the debug.log I can clear see the invoice ID remain the same value.

@joni-jones, I found payment will fail with message "cant place order" when items are set with custom option. Here is the message from system.log

main.CRITICAL: Exception message: Warning: Invalid argument supplied for foreach() in /var/www/public_html/www.mydomain.com/vendor/magento/module-catalog/Model/Product.php on line 1910

as I know there are issue with custom option, it's here #5573
