Unable to connect using external IP with Open console command

MajorFailure · September 19, 2017, 1:16pm

Hello,

I am unable to connect to a server using my external IP address. Connecting locally using the internal IP works fine. I have tried with multiple machines on my network and have tried with the server and client on the same machine and the server on one machine and the client on another etc.

Steps:

Create a blank project with 4.17.1
Close the Editor
Create a shortcut to run as server: <path to UE4Editor.exe> <path to project> -server -log
Create a shortcut to run as client: <path to UE4Editor.exe> <path to project> -game -log -windowed -resX=1280 -resY=720
Run the server
Run the client
Open the console on the client and type in: open <your external IP>

Server log:

My router is a Netgear D6220, firmware is up to date.

I have forwarded ports 7777 & 7778 for TCP and UDP to the machine running the server and set the Windows firewall to allow this through (also tested with the firewall turned off).

Any help would be much appreciated,

Thanks.

Hi
Same problem here too. I follow this tutorial for my dedicated server: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

But I can’t join if am using my public IP. I open the port 7777 on my router, I open my firewall with inbound and Outbound rules. etc, etc.

feiwu · September 25, 2017, 7:05am

from the log, the server can receive from the client,
but it seems like the client and server both send a lot of duplicate data, maybe your router have bug.

You can try put the dedicated server on cloud server.
I used run dedicated server on cloud server, and it works fine.

Atomfreak · September 25, 2017, 11:20am

Hi Feiwu. Thanks for the info. Any cloud server, you can recommend. My other question is does it need to be built on Linux to be playable via the cloud server?

feiwu · September 25, 2017, 11:23am

I used linode, yes, you should build dedicated server for linux. although there’s windows cloud server, linux server is much more cheaper and easy to use.

Atomfreak · September 25, 2017, 12:25pm

I will try on windows cloud server first like Azure. I just never build on Linux. But there is lot’s of good tutorial here. Thanks for your reply.
