API integration with Joomla and Prestashop

Hello,

I’m trying to integrate mautic with joomla module and I get this error when I click Authorise button:



The requested URL /oauth/v2/authorize?client_id=1_41kfxfyyhzuo48w4cw0co4ok8gg0gogkkg80o0owgc8s4csosw&redirect_uri=http://www.evc.pl/administrator&state=988e49cd534f4149a6b330bf5d29180d&scope=&response_type=code was not found on this server.





Ii also tryig to integrate mautic with prestashop using module from Zdeno Kuzmany. In this case after click Authorise button I see only this communicate:



Api Credentials are not valid. Please check it.



The credentials are valid of course.

I really don’t know what to do. Can someone help me?
