block from SSH and FTP

yesterday i was upload some images using filezilla to my VPS , and today when i tried to login into my VPS i got connection time out , same thing when i tried to access using FTP. but i can acces using another ssh with command ssh user@ips. and i have no problem accessing my website without any problem ,

im using centos 6.6 and CSF installed, i've tried to add my ip on csf.allow and csf.ignore but nothing change, i did checked csf.deny and host.deny but nothing there , it was empty.

is there a way to unblock my vps so i can connect with my local ip ?
