Can't connect on public ip on own server

I can't connect to my own server. Localhost is working. server.propeties are correctly. If i use couldyouseeme.org it says my port is not open. I am 100% sure i portforwarded. I disabled my firewall. So i don't know what to do! I am using craftbukkit 1.7.9.

Can anybody help me?

If I remember correctly, you should not need to put in the port if the port is 25565.

Are you sure you are using the correct external IP? Use this to get your IP and test if the port is open:
http://canyouseeme.org/

 

@Zombie_Striker It says that my port isn't open, but i am 100% sure that i port forwarded correctly...

 

@Impossiblepvp
Please try the following:

1. Run your server
2. Once it is online, use the website to see if the port is open then.
3. If it is not open, then make sure you open port 25565, set it to "both", and hit apply
4. Restart your computer.
5. Go back to step #1

 

I think i found the problem. I have two routers, but i don't understand how to port forward with 2 routers.... i am not so good at this topic so if anybody could help me?

 

I would assume you have to find the details of the second router and portforward it just like you did the first? Also I cant find craftbukkit anywhere on this to download could someone help? Haven't been on this in a long time!

 

1. This most likely would deserve it's own thread.
2. All versions of bukkit have been taken down (If I remember correctly). You would need to download spigot instead.
