Hello,

For the past weeks whenever I would connect to DigitalOcean and go to the console I would receive the following messages (https://ibb.co/pJyNCrD). I didn’t know what to make of them at the time but after some research, I found out that the firewall is blocking some connections.
I tried blocking some of them using “sudo ufw deny from IP” but there are so many of them. Is there another way to permanently block these connections?
Because they show up constantly they render the console unusable and after they started showing up, our server would constantly go down due to “Error displaying the error page: Application Instantiation Error: Could not connect to MySQL”.

Hi there @c4e,

As a quick fix you could sign up for Cloudflare, this would hide your Droplet’s IP address behind their CDN and also there is an option which you could enable in case of a DDoS attack.

Another thing you could do is to add a Cloud Firewall as an extra layer of protection.

Hope that this helps!
Regards,
Bobby
