I just setup a second PC to use as a game server box. After installing and launching SteamCMD I entered "login anonymous" let it do its thing. From here I entered "app_update 896660 validate" and it downloaded everything just fine. From here I was transferring my server/world files over from my primary PC that i used to run the server from. I opened ports 2456-2458 on my router but would always get a "failed to connect" message when joining the world.

If anyone runs into this issue, my solution was that I had to search for the world again and not use the one I had set as a favourite.

Looks like the dedicated server application ID (896660) is no longer available anonymously:

Steam>app_update 896660 validate
ERROR! Failed to install app '896660' (No subscription)

It's working on Raspberry Pi 4Gb using Windows 10. I've tested it. The main issue is unstable ping (80-200ms), so it's not comfortable to play. There are many things that can affects ping. I'm trying to exclude them. If it's happening because of arm64 > x86 compiler that's sad.

@Xilrat Yeah you can migrate the data over to a dedicated server instance, citadel have a guide here that may be of use to you: https://citadelservers.com/client/knowledgebase/365/Uploading-your-own-custom-Valheim-world-file-to-your-server.html

i have been running a game with friends on my pc, is there a way to have that game used as a server? we have built and done a lot with it.

How do you UNinstall to reinstall?

I am mostly having trouble with the port forwarding thing. I'm new to this stuff and just want to set up a server for me and my friend to play even when the other isn't available. Is anyone using a Spectrum RAC2V1S Router? I've figured out how to access it but all the guides I'v found are for different models and the interface is different and confusing to me when trying to follow the guides. Specifically I've been using the guide for Valheim on PortForward. Any possible help is appreciated.

So you mean that whatever number I put after -port, the game will add 1 to that number and that will become the query port? So if I use -port 8888, then query port would automatically be 8889? (Meaning I would need to make sure ports 8888, 8889, and 8890 are open/forwarded?)

So even though each server needs 3 ports in total, I only have to set the first number, and the game will automatically finish the other two numbers as I outlined above, I hope I have that correct?

(And thank you for taking the time to respond, I really appreciate it, and our community absolutely loves your game!)

query port is always the port after game port

We'd like to run multiple servers, as our first one is full most of the time, but I have a question regarding the ports.

Supposedly the game uses three ports (2456-2458), and all the 'how to set up your server' instructions only show using "-port 2456" in the instructions, as per above. Port 2457 is the connection port - but it isn't listed in the instructions, so how is it being assigned? Does the game take whatever number I use after "-port" and then just add N+1 and N+2 to get the other two numbers?

My concern is that when i go to make server #2, since I used port 2456 already, this time I'll use "-port 3456"... Will that automatically know I want to use ports 3457 & 3458 for the second server? Or can I use "-ports" with a range?

Like "-ports 3456-3458" ?

Or does it need to be comma separated values (CSV)?

Like "-port 3456,3457,3458" ?
