Hello guys,
After investigations, I was able to identify the problem.
As you are using FPM together with PHP, it is necessary to make some code changes:
- In the PHP project you must add the line in .htaccess:
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
- And to retrieve the Authorization header, you must call the variable:
$_SERVER['REDIRECT_HTTP_AUTHORIZATION']
I share the solution for everyone's knowledge.
Best regards
