This means that Ajenti port (8000) is used by other application. Check with 

sudo netstat -tlnp | grep 8000

I have the same problem and I have nothing on my 8000 port, and I tried all kinds of other ports
May be an old thread, but I cant seem to find a solution to his either. The netstat replies 
tcp        0      0 0.0.0.0:8000            0.0.0.0:*               LISTEN 
Btw, for those who are looking, I'm on CentOS 7 minimum install. To get netstat to work:
$ sudo yum install net-tools
Did I miss anything? I'm using the latest version as of today (1.2.22.3). I'd hate to start another topic. I'd be making a mess for helpseekers. Apache seems to be running so I should be close. 

Much appreciated in advance!

Run netstat with -p to see which process took the port.
If you're running with -p, but don't see processes, add sudo.
Thanks Eugene for your quick reply. I tried both:
$ sudo netstat -p | grep 8000
$ netstat -p | grep 8000
None of them replied anything. I previously tried 
$ nmap -sT -O localhost

8000/tcp open  http-alt
Is that of any help?
I mean that you need -p in conjunction with all previous options, e.g. sudo netstat -tlnp | grep 8000
This is what I'm getting as result:
tcp        0      0 0.0.0.0:8000            0.0.0.0:*               LISTEN      18538/python 
Looks like that solved the problem at some level. I'm getting this as results of ajenti-panel

Starting server on (u'0.0.0.0', 8000)
SSL enabled: /etc/ajenti/ajenti.pem
Starting new HTTP connection (1): meta.ajenti.org
I'm sure I've got ways to go, but at least this one is good (still "This webpage is not available". However, you pushed me the right direction. Thanks! If more issues appears, I'll make sure to put it in the right topic.
Probably firewall (blocks port 8000 in clean CentOS) or wrong URL.
It appears iptables got replaced with firewall-cmd. This is a working port opener.

firewall-cmd —permanent —zone=public —add-port=8000/tcp
firewall-cmd —reload
Oh and again, it's a CentOS 7 issue.

Pardon, I think I made a mistake. It was supposed to be double "-". So again:
firewall-cmd --permanent --zone=public --add-port=8000/tcp
firewall-cmd --reload
This should be it. Not that last post. My apologies.
This is what i got:
-bash: firewall-cmd: command not found

Please help, the same problem:

I have the same host - ISPconfig
