Error Paypal Production Mode

Hello, if my Paypal is marked as Production Mode (Projects -> Funding), in step 2 appears this error and don’t redirect:

Fatal error: Uncaught exception ‘PayPal\Exception\PPConnectionException’ with message ‘Couldn’t resolve host ‘AdaptivePayments” in /home/pushon/public_html/wp-content/themes/fundingpress2/funding/lib/paypal/paypal-sdk-core-php-811c13c/lib/PayPal/Core/PPHttpConnection.php:95 Stack trace: #0 /home/pushon/public_html/wp-content/themes/fundingpress2/funding/lib/paypal/paypal-sdk-core-php-811c13c/lib/PayPal/Core/PPAPIService.php(73): PayPal\Core\PPHttpConnection->execute(‘requestEnvelope…’) #1 /home/pushon/public_html/wp-content/themes/fundingpress2/funding/lib/paypal/paypal-sdk-core-php-811c13c/lib/PayPal/Core/PPBaseService.php(65): PayPal\Core\PPAPIService->makeRequest(‘Preapproval’, Object(PayPal\Core\PPRequest)) #2 /home/pushon/public_html/wp-content/themes/fundingpress2/funding/lib/paypal/paypal-adaptivepayments-sdk-php-1d55682/lib/PayPal/Service/AdaptivePaymentsService.php(256): PayPal\Core\PPBaseService->call(‘AdaptivePayment…’, ‘Preapproval’, Object(PayPal\Types\AP\PreapprovalRequest), Object(PayPal\Common\PPApiCo in /home/pushon/public_html/wp-content/themes/fundingpress2/funding/lib/paypal/paypal-sdk-core-php-811c13c/lib/PayPal/Core/PPHttpConnection.php on line 95

Remember that just happens when Production is marked. When Sandbox is marked, goes right.
