When I'm accsessing 000webhost File Manager its always redirecting me to the Log In session always and always, sometimes I even cann't Log In to my File Manager, any solutions?

Try turning FTP on/off in Settings > General.
If that doesn’t work, hit the Repair button in Settings > General.

I’ve tested your account and FTP is working fine and the File Manager should login automatically now.
Try logging out of 000webhost.com and clearing browser data first.
