Hello,
I am trying to install the latest version of Matomo in our Nginx / Unit stack. I received an error message but cannot find the problem.
After successful installation I got the typical Matomo login page. I use the correct credentials and submit the form. Now the registration page is reloaded from “/” to “/? Module = Login” and the registration form suddenly contains the registration form … so I now have a registration page with two registration forms.
I have analyzed the call to the registration form and received the following 403 return:
Error: Form security failed. Please reload the form and check whether your cookies are activated. If you use a proxy server, you must configure Matomo to accept the proxy header that forwards the host header. Also check that your referrer header has been sent correctly.
The message contains a link to the FAQ - https://matomo.org/faq/how-to-install/#faq_98 - but the information described is sent from the top-level Nginx web server to the device and the PHP 74 interpreter on my phpinfo ().
The cookie used is correct and the CSRF token used is also correct.
I activate the debug function, but I don’t get any information about this error …
Now I’m a little tired and hope that you can help me find the problem.
best regards
