The jar file is directly downloaded from minecraft.net yesterday, so i don't think its corrupted. Unless your saying it could be a compatibility issue with the jar and Ubuntu server?

Want to add that the server is runs fine for a while but when nobody is no it it tends to stop. Don't know if just anybody has been online on it when it happens or if its some type of inactivity thing.

check so that your router ip is the same as your public ip. if not then contact your ISP

Hi,

I'm having server stability issues, the server keeps on shutting down after a while being up and i have no idea what is happening.

I'm using a dedicated ubuntu machine for the server and using SSH to access it.

could it be when I'm closing the SSH portal or could it be a BIOS or OS setting?

Also if someone could tell me what the first main/warn is about too?

Thanks in advanced!

* ip stuff removed

Hahaaa i solved it(I think), and it wasn't my fault really, as i had no idea about this:

https://en.wikipedia.org/wiki/Carrier-grade_NAT

The ip i got was not a real public ip and therefore it wasen't possible to connect to my router, i got stuck in the isp level.... so stupid.

I haven't tried if it works yet... as the public ip hasen't had time to update from the isp from when i called them(hoping this solves it!).

EDIT: Yep, it was the issue, now it works finally!! hope this info helps other people!

Yes, it can. Pinging google.som was possible and more, so it can reach the internet. But i tried pinging the routers external ip from outside the network(the routers ping funktion was enabled) but i dident get a response. So both no respons from the router and when checking the port 25565 from wan it says closed too, any ideas?

EDIT: its more or less the same problem but i dident f*ck up the ip

https://bukkit.org/threads/cannot-open-port-25565.134926/

Haha sorry, the ip in the port forwarding picture is just changed for the picture. Its set to a 192.168.1.xxx ip in reality.Sorry about that

And yes the ip in the ubuntu machine is configured to have the static ip only too, and it's possible to connect to the server on LAN.

:SOLVED:

The problem was the isp used NAT for their network ISP when delivering internet and what i got was not a real public ip and therefore it wasn't possible to connect to my router externally, i got stuck in the ISP level. Hope this info helps other people! Easy way to check this is to compare the wan ip on the router and your ip on https://whatismyipaddress.com/

if its not the same then Carrier-grade NAT can be the case (unless it's the modem somehow hogging the public one).

Thank you those who where trying to help! Now finely i can farm in peace

Hello, I am setting up a public server on a dedicated Ubuntu machine. I have been trying at this for over a week now. I have exhausted all possible routs i can find/imagine on what the problem can be. I have scourge the Internet, the FAQ, previous posts and more. I cant seem solve it whats causing the problem. remote connections to the server dosen't work, only get the io.netty connection timed out error(I use the phones hotspot to connect externaly to the server when testing and connecting to the external/public ip of the router(tried both "ip":25565 and just "ip").

Port forwarding:

Using standard port: 25565 and the server ip

(the server ip is set to static in the router as well)

Router model: RT-AC68U

See attached picture

Server.properties:

the server ip is left blank

the port is set to 25565

See attached picture

Internet speed is good

picture is from a wifi conection, The server is connectd via a ethernet cable to the router, there is a switch inbetween server and router fyi.

I tried hosting the server on the laptop with wifi and it dident work either so im thinking its not that. most likely the router side.

See attached picture

server firewall:

the server's fire wall is deactivated, and if for some reson it where to be it I did make exceptions for port 25565 on both udp and tcp

The router is connected to the fiber Internet directly. No other device in between.

I tried checking if the port(25665) was open (while the server was running) and it was NOT. So something is funky here.

I used http://ismyportopen.com/

see attached picture

Did i forget any other info that is useful?
