Setting up on a VPS unable to register

I setup on Bitwarden on a VPS. Now I am able to access the " Register " page. But when I enter everything and click " Submit " nothing happens.

In the console, it says

Content Security Policy: The page’s settings blocked the loading of a resource at eval (“default-src”). 10 core.js:5257:15

Angular is running in development mode. Call enableProdMode() to enable production mode.

It would be nice to know how to fix it. Thanks.

You can get in contact with the bitwarden team at Contact | Bitwarden

Hi, enkih,
ich will auch Bitwarden auf einem VPS (Cloud-Server von IONOS) einrichten.
Hilfst Du mir dabei ?
