ACP API Config Issue NGINX since Update 4.6.12

[ZLTRGO]

Hi,

I have this issue since I update to the newer versions of IPB:

It was working fine before, but now I can't get passed this page.
I tried to add the needed file to the folder and gave it 755 permission but that didn't help.
I tried to use the "NGINX" config version that worked before without issues but that didnt work either, config:

location / {

    location /api/ {
        if (!-e $request_filename){
              rewrite ^/api/(.*)$ /api/index.php;
        }
    }

    if (!-e $request_filename){
         rewrite ^(.*)$ /index.php;
    }

    try_files $uri $uri/ =404;
}

^ ^ ^
This is also the default Rewrite config of my whole website settings in NGINX and it always worked in the past without issues, even with the API.

Any ideas?
