Sofort Payment Module and Paypal are not working correctly anymore

[mium]

  hello guys,
  
  i have a urgent issue. Since today when the client pay by paypal on mobile device. after payment he sees just a white page and no order confirmation page. And i also will not get the order in presta shop backoffice. But the money is coming on paypal.. Why is this like that `?
  
  Also the "sofort payment module" is just working on desktop pc but not on mobile device.. the error is: the input hash is not correct. But on desktop device its working.

• this error comes before paypal payment in debug modus :
