Solved No One Can Join My Server

I created a server a while a go and used uTorrent to let other people on and it worked for a while... but then just suddenly one day it stopped working and no one could join it unless at my house. If they tried it just said java.net.ConnectException: Connection Refused: no further information: .So then i downloaded Simple Port Forwarding and that worked perfectly for a few days but then it stopped working again. I did update my IP. At the moment whenever i use canyouseeme.org it says No route to host. Whenever i use Simple Port Forwarding's Port Tester it says:
Port: 25565 TCP
Status: Port in use
Open?: Failed

 

When you portfoward, you use your IPV4, it may have changed,
Open CMD type /ipconfig and look

 

I did update my Ipv4 when I port forwarded. I also updated the ip i gave to my friends (from ipchicken.com).

 

Can anyone help me please because I've got one comment and I posted this a long time ago.

 

33CoolyDude33 I've no idea why you would use a torrenting program to try and run a server but moving on...

It sounds like something is using port 25565 already. Depending on your OS there are ways to find out what's using a specific port: Google search for those instructions. Also bare in mind that I have no idea what "Simple Port Forwarding" is.

 

Seems I port forwarded wrong (typo) but now I fixed that and it does the same thing except now it says:
java.net.ConnectException: Connection Refused: no further information
and canyouseeme.org says connection timed out

 

I am looking for how to see what is running on 25565 now but I'm finding it hard. Simple Port Forwarding is a program you can download to port forward with.

When I type netstat -a | find ":25565" into CMD it says:
TCP 0.0.0.0:25565 [my computers name]:0 LISTENING
TCP 127.0.0.1:25565 [my computers name]:49345 ESTABLISHED
TCP 127.0.0.1:49345 [my computers name]:25565 ESTABLISHED
TCP [::]:25565 [my computers name]:0 LISTENING

But when I closed my server (I have a bukkit GUI server) and minecraft and typed netstat -a | find ":25565" It came up with nothing
Can I have some help anyone?​

 

33CoolyDude33 Maybe this "Simple Port Forward" is what's causing it - maybe it tries to bind 25565 at the same time as Minecraft does?

 

Ok. This is what I did:
1. I uninstalled Simple Port Forwarding and utorrent then re installed utorrent
2. Set up the preffrences thing for port 25565
3. Used canyouseeme.org to test my port and it said: Success: I can see your service on 81.243.134.1 on port (25565)
Your ISP is not blocking port 25565

I have no idea what the problem was but it looks like its fixed I will get a friend to try and join it ASAP and if it doesn't work I will tell you.

 

Do you have a windows firewall, if yes add tcp port 25565 or deactivate it
