Problems with payments pp_pro

Hello! There were problems with online payment.
I use standard module pp_pro. After entering credit card data, payment takes place, there is a window "please wait", and it disappears! User does not redirect to the page "Thank you for your order".

Version 2.1.0.1.1 opencart
The problem appeared after connection ssl or after the server migration.
Errors in the logs:
