Could you share a screenshot of the red "Dangerous site" warning, including the full URL shown in your browser's address bar? That tells us whether the warning appears on the Railway dashboard itself or on one of your deployed app's domains, and which browser or security tool is showing it.

i think deployed app

The address in your screenshot is the Railway-provided domain of a service in your own workspace, not the Railway dashboard. The warning applies only to that app's address, and the dashboard is still at railway.com/dashboard.

The red "Dangerous site" page comes from Chrome, not from us. Its "Details" button shows the reason Chrome gives for flagging the address.

so what should i do now?

Your Railway dashboard isn't affected, so you can keep using it at railway.com/dashboard. The warning applies only to that app's address, and it comes from Chrome, so we can't remove it on our side.

Click "Details" on the warning page to see why Chrome flagged the address. The "Learn more about this warning" link on that page explains Chrome's warnings.

The details in your screenshot show that Google Safe Browsing has flagged your app's address for phishing. This warning comes from Google, so we can't remove it on our side.

If the app is yours and isn't meant to collect logins or payment details, check that its pages and code haven't been changed by anyone else. Then use the "Let us know" link on that warning page to ask Google to review the address. Your Railway dashboard itself isn't affected.
