I have a Debian Squeeze VPS. I have set it up with Apache 2.0 and such. Problem is, now I can't access it anymore through my home Internet connection. When I attempt to access the web server through my browser, it just times out. When I do a ssh -v I get:

OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011

debug1: Reading configuration data /etc/ssh_config

debug1: /etc/ssh_config line 20: Applying options for *

debug1: Connecting to (SERVER IP) [(SERVER IP)] port 22.

debug1: Connection established.

debug1: identity file ~/.ssh/id_rsa type 1

debug1: identity file ~/.ssh/id_rsa-cert type -1

debug1: identity file ~/.ssh/id_dsa type -1

debug1: identity file ~/.ssh/id_dsa-cert type -1

And then it hangs, and finally tells me Connection closed by (SERVER IP).

I have tried to access it through another machine using a different connection, and it works perfectly fine, as it should.

I can ping it through my own machine, which is MacBook Pro 13" running OS X 10.8 (Mountain Lion).

I have checked /etc/hosts.deny on my server, and it does not mention anything. How can I resolve this problem?

UPDATE

Having restarted my router, my IP address is now a different one, and now I can (probably due to that fact) access my server again. I am however, still curious to know the cause of this.

It's possible you have a monitoring tool like Fail2ban which blocks an IP address after multiple failed attempts.
