After you have uploaded the Komment extension via the QMC you need to make a small change to the content security setup. So navigate to the menu item Content Security Policy => In the top right corner press Add => In the Directive section select connect-src and connect-src (web-socket). In the Origin write app.cryptolens.io
. You can provide a name of your own choice - e.g. 'Komment'. Finish by pressing Add.
