Question

Attack Detected - Blocked because of an intrusion attack

Hello, today I added a subdomain to my server. An nginx proxy is running in the background and I’m passing data from an API. I prepared everything and did ssl authentication with certbot. However, when I tried to access my site, I got the “Blocked because of an intrusion attack” warning. I searched for a solution to the problem but couldn’t find it. I am using Ubuntu droplet. In several forums they said that the source of this error is the provider (Digital Ocean). How can I solve this problem? The error screenshot is below.

Blocked because of an intrusion attack

Your computer has been blocked because an intrusion attack originating from your system was detected. For more information, contact the system administrator.

Hello there,

As mentioned it’s unlikely to be coming from DigitalOcean.

You can examine the server access logs and check for malicious requests and general spikes in the load on the server in order to determine whether there was an issue related to a vast amount of traffic or not.

Hi there,

This is quite unlikely to be coming from DigitalOcean.

Can you confirm the following:

  • Are you using a VPN? If so does it work without you being connected to the VPN?
  • Are you accessing the server from a corporate network? If so have you tried accessing the site from another network like your 3G/4G for example?
  • Are you using Cloudflare? If so, can you try disabling it for a moment and try again?

Let me know how it goes!

Best,

Bobby
