We use Google services (Firebase) for our authentication/account creation. It's possible that the firewall is blocking access to that service, which we are working to resolve. In the meantime, you can try registration over a VPN.

If you are still encountering issues, you can reach out to customer support by clicking on the question mark in the bottom right corner of the Blush web application or by emailing us at hola@blush.design, and we will help you as soon as possible.
