Suddenly lost access to FTP

All of sudden I can’t connect to FTP site.
I seen current closed thread, did all trouble shooting. I even deleted, repair website, but to no awail
I can’t login to File server either from website or from FTP Client
Please help.
my FTP client gives me following error
Connection timed out after 20 seconds of inactivity

Please help!

Basically wait it out, if you’ve read the troubleshooter you’ll understand the timeouts/error codes generally indicate FTP server issues, and the “Login details not correct” on File Manager confirms this.
