npmjs Admin Dashboard Broken Due to Content-Security Policy Violation

Bug

Body

I’m experiencing an issue with the npmjs admin dashboard where it fails to load correctly due to a Content Security Policy (CSP) violation. The browser console shows the following error:

Refused to connect to 'https://static-production.npmjs.com/styles.4ddf61b895c5feda30f4.css.map'
because it violates the following Content Security Policy directive:
"connect-src 'self' checkout.stripe.com https://checkout.stripe.com
https://billing.stripe.com/sessionhttps://api.funcaptcha.com
https://api.arkoselabs.com sentry.io api.github.com www.npmjs.com".

This appears to be preventing some parts of the dashboard UI from functioning properly.

Thanks for the clarification. I understand that the dashboard is maintained by npm, Inc., so this issue cannot be fixed on our side.

After additional testing: It works when I use my mobile network to connect but not my normal internet connection;
so I assume some kind of network level blocking going on.

Just use the mobile hotpot, it works well...

Refused to connect to 'https://static-production.npmjs.com/commons.149ed37e6f8137f65e39.js.map' because it violates the following Content Security Policy directive: "connect-src 'self' checkout.stripe.com https://checkout.stripe.comhttps://billing.stripe.com/sessionhttps://api.funcaptcha.comhttps://api.arkoselabs.com sentry.io api.github.com www.npmjs.com".

same thing when logging in after changing password!

[shiny]

still same error. this is crazy

[fpsqdb]

same error occurs even after clearing cookies or using incognito mode.

[aaurelions]

It's true. I can't perform any actions, I can't even log into my account because the menu on the right won't open. The interface won't let me configure Packages and scopes.
