• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

Issue CORS: "Only One Origin Allowed"-Error - where does second origin * come from?

I

it78croix

New Pleskian
Server operating system version
Ubuntu 22.04.2 LTS
Plesk version and microupdate number
Plesk Obsidian Web Host Edition 18.0.53 Update #2
Having a Backend NodeJS-App on api.XXX.com and a Frontend React-App on XXX.com.

On the BackendNodeJS-App and in Plesk - Domains - the Apache & nginx Settings my 'Access-Control-Allow-Origin"-Header is set to the frontend url.

But, I get the message of

Access to XMLHttpRequest at [api] from origin [Frontend] has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains multiple values '*, [...], but only one is allowed.
Click to expand...

I can't find where the 'Access-Control-Allow-Origin'-Header could be set to the asterisk ('*'). Any ideas?
