Issues with OAUTH Access

Hello everyone,

I have a telephone software that provides an interface to SuiteCRM. For this, we need to create a client in Suite with Secret and ID. Unfortunately, the access is repeatedly denied. The logs in SuiteCRM show the following errors:

Error 500 POST /Api/access_token HTTP/1.0
Warning mod_fcgid: stderr: PHP Fatal error: Uncaught LogicException: Key path "file:///var/www/vhosts/" does not exist or is not readable in /var/www/vhosts/
Warning mod_fcgid: stderr: Stack trace:
Warning mod_fcgid: stderr: #0 /var/www/vhosts/ League\\OAuth2\\Server\\CryptKey->__construct()
Warning mod_fcgid: stderr: #1 /var/www/vhosts/ Api\\Core\\Resolver\\ConfigResolver::{closure}()
Warning mod_fcgid: stderr: #2 /var/www/vhosts/ Pimple\\Container->offsetGet()
Warning mod_fcgid: stderr: #3 /var/www/vhosts/ Slim\\Container->get()
Warning mod_fcgid: stderr: #4 /var/www/vhosts/ in /var/www/vhosts/ on line 45

It seems that the private key private.key either does not exist or is not readable. Do I need to make any fundamental settings in SuiteCRM or the system to resolve this issue?
System ist 7.12.5

Thank you in advance for considering this.

Best regards,

what permissions /ownership is your public and private key currently?

Did you follow these steps for setting up your private and plublic keys?
