Permission denied when trying to access metrics

[dstathis]

I installed the plugin and configured wp-config.php but when I go to https://<my-url>/wp-json/metrics?all=yes&prometheus=<my-key> I get the message { "error": "You cannot access to that page" }. How can I fix this issue?

Did you configured in the settings panel the key?
Seems that the readme is not updated, I will update it now.
