need solution for this "Inbound DDoS Detected"

Hi there,

Our system has automatically detected an inbound DDoS against your droplet named xxxxx with the following IP Address: xxx.xxx.xxx.xxx

As a precautionary measure, we have temporarily disabled network traffic to your droplet to protect our network and other customers. Once the attack subsides, networking will be automatically reestablished to your droplet. The networking restriction is in place for three hours and then removed.

Please note that we take this measure only as a last resort when other filtering, routing, and network configuration changes have not been effective in routing around the DDoS attack.

Please let us know if there are any questions, we're happy to help.

Thank you,
DigitalOcean Support
