Normally we tend to get requests from clients that they no longer are able to access their website!
99.99 % of the time this is due to their IP being blocked on the firewall (the other .1 % would be server issues which we would already be aware of since we have 24/7 Pro active monitoring)
One of the main reasons of this is due to the client having multiple sessions of FTP open…in other words they are already using FTP to upload their files and they happen to have another few sessions open
The server interprets this as a Brute Force attack..which basically means that if things someone is trying to flood FTP thus blocking the IP address
If you find this is the case all you need to do is contact us Email us (Clients should already have backup email addresses to contact us on) instead since if you are blocked then all the sites on the server will be blocked including the support site
For System administrators and those with dedicated servers login to SSH and run the following
then find the IP in the deny_hosts.rules file and remove it then save it
then you need to restart APF (APF being the firewall service)
service apf restart
and you should be able to get back on!
