Server not binding to Port 28015

Hey!

I wanted to open up my Rust dedicated Server to some Friends to play around.
I'm using a Dynamic IP from noip.com and setup the Server with ip 0.0.0.0 and Port 28015 and RCON port 28016, as suggested in many guides and forwarded these specific ports.

So my Problem is when someone tries to connect to the Server with hostname:28015 it does not work.
I also tested the ports and if the IP is working and came to the conclusion that both ports are at least open and the hostname also works however if i try to connect to the port 28015 on canyouseeme.org i get the message connection refused (if firewall turned on i get connection timed out). Port 28016 is working without an issue.

I'm sorry for my bad english but i think it is understandable
Hopefully someone can help me with my problem.

 

Did you allow them in windows firewall and any other security software you are running

 

Sounds like you maybe open port 28015 TCP? you should check that you forwarded 28015 UDP, rcon uses TCP.

 

Ok i just checked again and i allowed them. Also i forwarded TCP And UDP on both ports but i don't know if that could be a problem?

 

Nah, then you should be okei. you can not use canyouseeme.org for test udp ports, that site has only support for tcp.
