Error 421 too many connections (8) from this IP mostly happens when you open a new FTP connection without closing idle connections. If you are using shared hosting, this error may occur because your hosting provider limits simultaneous FTP connections to prevent server overload.
What is error 421 too many connections (8) from this IP.
This error “Too Many Connections (8) from This IP” means that the number of connections to the server from a certain IP address (the IP mentioned in the error) has reached the maximum allowed, and the server is not able to make more connections.
This problem usually occurs in network environments, and is likely due to one of the following causes:
- Excessive Queries: If requests are sent to the server repeatedly from a particular IP, this may result in a high number of connections.
- Brute force attacks: Brute force attacks or attempts to log in using user credentials may increase the number of connections.
- Using automated tools: Programs or tools that establish connections to the server automatically may cause this error.
To solve this problem, you can take actions such as:
- Checking network activities from the client (user or application) using monitoring tools.
- Increase limits for connections from a specific IP.
- Applying more intensification for surveillance or punishing surveillance attacks.
In any case, it is important to perform a detailed analysis to determine the cause and apply the appropriate adjustments. Well, now that you know the cause of this error, let’s learn how to fix it.
