Have you looked in the apache logs for any anomalies? In the absence of any error messages to the screen, that would be the next place I'd look. Also, if you're running a firewall, check the firewall logs, if any.

You are probably blocked in the firewall. I have seen this happen, when you have configured your FTP client to use passive FTP ports, but these ports are not open in the server's firewall. This will often be detected as a port scan, and your IP address can be subsequently blocked. You can check iptables with this command (assuming you can access the server form another location)

iptables -nL | grep x.x.x.x

Where x.x.x.x is your IP address. If you don't know what your IP is, you can check at a site like http://whatsmyip.org or similar.

If it isn't iptables, it may have added you to a deny file somewhere in the apache configuration, or in htaccess. Try this:

fgrep -RiH x.x.x.x /path/to/apache2/conf.d/*

x.x.x.x is again your IP address. Lastly, check your htaccess files for the site:

find /path/to/docroot/ -type f -iname .htaccess -exec fgrep -H x.x.x.x {} \;

thanks for both of your respnses.
I looked at all my logs nothing out of the ordinary that i can see.
i have no firewall running. Ubuntu 10.10 gnome i believe firewall is disabled by defualt. correct me if im wrong. (and i disabled manually to make sure along time ago)

Wanted me to sudo it but nothing happened


Try this:

fgrep -RiH x.x.x.x /path/to/apache2/conf.d/*

x.x.x.x is again your IP address. Lastly, check your htaccess files for the site:

Changed my path to etc/apache2/conf.d/* and still nothing happenned.

find /path/to/docroot/ -type f -iname .htaccess -exec fgrep -H x.x.x.x {} \;

Didn't know what you were talking about here.

Also i tried pinging the server from my router it times out 4 times.
I try it from a websit like pingtools and it shows it accepting connection.
Now if I go to the server and log into the router and ping my router it does the same thing times out.

So what im thinking is that one of the routers is blocking the ip or website. i see nothing being blocked on the router at the server.
So im going to look at my router tonight when i get home to see if theirs any blocking going on.

See what im doing is using two comcast buseness accounts. one for a website forum and my hlstats for a tf2 game server.
then on the other account i have just my tf2 game server running.
now i need then to communicat cus the hlsats reads logs being sent from the game server and builds stats off them.
Is it posible comcast could block something like this? they told me it wasnt a problem to do what i want.
Just a idea. IDk im really at a loss. everything was working tell the upload with filezilla stopped.
Also i was reading that this has happened to others and that after 24 hours they were able to re establish a connection to the lite they got blocked out of. i really hope thats the case here. but im looking for help if any one has any thing on this thanks alot.

Edited to say

Ok guys thanks for all the help.
so i came home on my lunch and checked out everything and its been 24 hours since i was locked out so now it all working again. weird. some thing locked me out for 24 hours. ill have to be more careful.
thanks for all the help again.
this place is awesome.

If you're using the root acct (a bad idea BTW), then it's prob something like 'fail2ban' or possibly a PAM module.
People are always trying to break in with 'typical' admin acct names eg root, admin, administrator etc etc.
