When you land on a site and see a raw Azure 404 error page, that is already a strong signal that this isn't a functioning business. But the deeper problem with waws-prod-bn1-207-3057.eastus2.cloudapp.azure.com is that even if it did load, you could not trust the connection. The SSL certificate is invalid β it was issued for a different Azure domain name, meaning the encryption is broken. Any information you sent would be visible to third parties.
There is also no way to figure out who is behind this URL. No about page, no contact details, no social media presence, and no company name. The domain itself is an auto-generated Microsoft cloudapp address, not a real website name. Legitimate online services always use proper domain names and provide clear ownership and contact information.
The site also lacks a privacy policy or terms of service, which is a must for any service that interacts with users. Combined with zero history in web archives and no reviews anywhere, there is simply no evidence that this URL is part of any real project. Is waws-prod-bn1-207-3057.eastus2.cloudapp.azure.com a scam? The safer question is whether it is anything at all. Right now it looks like an abandoned or misconfigured backend server with no purpose and no protections. You should avoid it entirely.
