ℹ️ Support

Hello, I’m getting this error in my browser console.

NC 27.0.1.
PHP 8.1
Mysql 8.0
Default Nginx config from Nextcloud.

ServiceWorker.js:31 Refused to create a worker from 'https://cloud.example.com/index.php/apps/files/preview-service-worker.js' because it violates the following Content Security Policy directive: "script-src 'nonce-Q2757lreGFvNk5lQksvQ3QwVnc37775JGRWd3QjljMlltSURNOVZoM75757G9kNlRRdHI4TXcySzhtM3dnd1kxQnkwenRjUHdHUkxReEVKYjJ0L1lIWT0='". Note that 'worker-src' was not explicitly set, so 'script-src' is used as a fallback.

Would also like to know, discovered this error today. I don’t know since when the error is displayed.

Same here !!
it seems that it is linked to some favicons display issues and slowdowns

In the console i get

ncp_issue-obfuscated
ncp_issue-obfuscated1044×282 62.3 KB

Is there anybody to explain these errors ?

I am having the same problem, the weird thing is that is doesn’t happen on mobile or in mobile dev tools view on desktop.
