After upgrading to v3.0, I got DDOS attack, my application and everything is unrecoverable

anyone who have solved this.

I currently in contact with DigitalOcean support but I m not getting any result

V3.0 isn’t “Stable”, it is a development build.
The latest version is 2.3.8
3.0 also doesn’t have the latest patches against the latest attacks.
You have to revert back to 2.3.8 or start over.

Thank you, I started over thank god I had a backup of the data.
