Hi,
I'm hosting an API on a OVH VPS(Ubuntu 18.04) and clients send atleast 10 requests a second, sadly, they have now all been blocked from connecting, and firewall rules have not helped, any help?
These are some of the few reasons:-
-Viruses
-Bots
-Unauthorized device or service on network
-Illegal file sharing
-Spamming
-FTP servers on non-standard ports
-SSH brute-forcing
Hope this information was helpful to you.
