No other users can join any server i make

[Jamison_McKinney]

OS Name/Version: windows 11 pro

Product Name/Version: (Always use the full version number - not ‘Latest’)
AMP 2.4.4

Problem Description:
others cannot join my server, i can join my own on a separate computer within my house. originally, we were attempting this with mods but even after creating a new server without mods they cannot join, they weren’t even prompt for entering a password. what do i need to do or what should i be checking for? nothing seems obviously wrong

Steps to reproduce:

none, even starting a fresh server without mods and they still cannot join

Actions taken to resolve so far:
not sure what to be checking for this

i made a post two days ago about this but the forum wont let me reply anymore because “An error occurred: Please wait for other users to participate before replying” but here’s the situation so far and i hope someone can help me. i think i just aggravated the person trying to help me out cause they just quit responding or too busy helping other people out but anyway…

i was refered to with this link Diagnosing Connectivity Issues - Docs - CubeCoders Support so i followed the steps there with theres results…

ive made sure the application runs, which it does, no issues there.

i checked to see if the application is lsitening using the command prompt ampinstmgr ports valheim01, it shows 3 ports that are all listening.

next i checked the fireall rules using ampinstmgr dumpfirewall which looked ok. for shitsNgigs i also used ampinstmgr updatefirewall which produced this error.

and on my router i portforward 2456-2459 to my PC

so to my understanding everything seems like its working fine and people should be able to join my server but nope…

what am i doing wrong?

Hi Jamison,

Just a couple of questions for you.

When you said you port forwarded. Which protocol/s did you forward? As you can see there’s a mix of TCP and UDP that your server is listening for. Are you sure you are forwarding both?

Secondly, is your server/pc configured to use DHCP? If it is, have you reserved your MAC address a specific IP to use? If you’re using a dynamic IP your router will continue to forward ports to whatever address you plugged in and won’t update it if your PC gets a new address.

I’d also suggest getting someone to run a portscan on your public IP and confirm if they can see the ports are open. Use something like nmap (zenmap if on windows) or even just try a powershell line of

Test-NetConnection -Port 2456

I hope this helps you out. Good luck
