Issue with ports

[Daguima-dag]

Hi! First of all thanks for your amazing work. I asked this on Youtube but thought it best to ask it here. So, I followed your tutorial and have the server running on Digitalocean. But for some reason I just can't get port 2456 open. Port 2457 is open but 2456 and 2458 are closed (checked with the port checker you linked). Is there anything more to opening ports in DigitalOcean than editing the YAML file and running "netplan apply"? I tried adding rules to ufw and enabling it, but it didn't make much of a difference. I also tried activating Digitalocean control panel's firewall. Neither worked. I actually was able to connect the game to the server once, but it seemed totally random.

Same on mine but I have zero issues.

So I am confused why you are experiencing issues.

Our Discord has a lot of people helping each other out on issues out the script.

I know this issue has been closed, but I've reached out via Discord with no help as of yet. I feel like I'm running into a similar issue as the OP.

I first attempted using ufw but quickly realized I'm a lot more familiar with iptables so that is what I'm using in the output below. And just to clarify, ufw has been disabled:

# ufw status
Status: inactive

To rule out any issues with ports, I went ahead and configured the firewall to allow any traffic on any port on any network interface with any protocol:

# iptables -nvL
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination
 1063 63659 ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 952 packets, 154K bytes)
 pkts bytes target     prot opt in     out     source               destination

When looking at the services that are actively listening on ports, I do not see the Valheim server at all:

# netstat -ntpl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN      572/systemd-resolve
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      727/sshd: /usr/sbin
tcp6       0      0 :::22                   :::*                    LISTEN      727/sshd: /usr/sbin

However when I look at all services and their ports, I do see that port 2457 is active, but not in a LISTEN state:

# netstat -npl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN      572/systemd-resolve
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      727/sshd: /usr/sbin
tcp6       0      0 :::22                   :::*                    LISTEN      727/sshd: /usr/sbin
udp        0      0 127.0.0.53:53           0.0.0.0:*                           572/systemd-resolve
udp        0      0 0.0.0.0:2457            0.0.0.0:*                           1532/./valheim_serv  < - -
raw6       0      0 :::58                   :::*                    7           570/systemd-network
raw6       0      0 :::58                   :::*                    7           570/systemd-network

When I run the Valheim port checking tool on geekstrom.de, I see that port 2457 gets the OK, but not 2456 or 2458.

I have no other external firewall applications such as the built-in tool within the DigitalOcean dashboard.

Some additional information if necessary:

Provider: DigitalOcean
OS: Ubuntu 20.04.2 LTS

If you have any ideas or input, it would be greatly appreciated.

type

ufw enable

see if anything changes.

Worst case... PM me in Discord and I will screen share with you and we can do it together and figure out what is really going on.

Hi! Just letting you know that I was able to connect to the server through port 2456, even though only port 2457 gets the OK. Everything seems to be running fine. I noticed that I could connect to the server once but after logging out it didn't work. But I noticed that if I go back to the first Menu screen and then back to the JOIN IP button, it works. It looks like the issue I was having is probably a bug with the JOIN IP feature not refreshing after logging out once.
