    I'm still experiencing this issue despite following the "Resolution" step by adding the 2 lines to the additional nginx directive. I've applied this to the domain in question that is using Wordpress and the OneSignal Plugin and am still getting: A bad HTTP response code (403) was received when fetching the script.
    /wp-content/plugins/onesignal-free-web-push-notifications/sdk_files/OneSignalSDKWorker.js.php?appId=[myAppIdWouldBeHereButImHidingIt] Failed to load resource: net::ERR_INVALID_RESPONSE

    @Ben Hayes Click on "Check Security" button for the WP instance in Plesk and check if "Security of the wp-content folder" check-box is enabled or not. Disable it and check if the issue is gone or not. If the issue is still there then the cause is different than described in the article.

    Also, check this article https://github.com/OneSignal/OneSignal-WordPress-Plugin/issues/65
