I am not able to authorise the Joomla plugin to use Mautic API over OAuth2. Code: ERROR plg\_mautic PLG\_MAUTIC\_ACCESS\_TOKEN\_NOT\_VALID INFO plg\_mautic Authorize method called. When doing so I need to login to Mautic and then get redirected back to Joomla with a state and code in the URL ending up in a 500 Error: Code: 302 https://web01.mydomain.net/?plugin=mautic&authorize=true 302 https://web01.mydomain.net/en/?plugin=mautic&authorize=true 302 https://www.mydomain.ch/ma/index.php/oauth/v2/authorize?client\_id=6\_64\*\*\*&redirect\_uri=https://web01.mydomain.net/&state=f8a\*\*\*&scope=&response\_type=code 302 https://web01.mydomain.net/?state=f8a\*\*\*5&code=YjR\*\*\* 500 https://web01.mydomain.net/en/?state=f8a\*\*\*&code=YjR\* What could cause that error?
