Valheim server doesn't return player info

[kaltinril]

I get back no information for the player's connected in Valheim. Before I go digging through the code, suggestions?

>>> import a2s
>>> address = ("localhost", 2457)
>>> a2s.info(address)

Yeah same here. Here is output of my test script on 189.1.168.21:26921:

It seems like valheim isn't responding to rules request (see https://developer.valvesoftware.com/wiki/Server_queries#A2S_RULES). Sadly there is nothing library can do with such case.

@Nereg Thanks for being so quick to help others!

If the server is not responding to the request there's nothing I can do about it. If the game has a player list somewhere in the server browser I might be able to help you to reverse engineer that, but that's out of scope for this particular library.

Well, now I tried to get this working but get similar problem - only that it's showing with a2s.info too:

>>> import a2s
>>> a = ("localhost", 2457)
>>> i = a2s.info(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.9/dist-packages/a2s/info.py", line 182, in info

  File "/usr/local/lib/python3.9/dist-packages/a2s/a2s_sync.py", line 22, in request_sync
    response = request_sync_impl(conn, encoding, a2s_proto)
  File "/usr/local/lib/python3.9/dist-packages/a2s/a2s_sync.py", line 28, in request_sync_impl

Can you get player list/server info from LAN tab in Steam server browser? If not then library can't help because it implements protocol which is used in the browser.

[jensbrak]

It works just fine for me. Now.

Not sure why it started to work but maybe it is how the server is started or perhaps it needs a while before responding. I have to dig som more to get to know the workings of the Valheim server I run. But it does work now.

I am getting this same problem with a Valheim server I am running on linux.

if u do ping localhost command or server ip => you will get 64 bytes from localhost icmp_seq=1 ttl=46 time=162 ms (DUP!)

the (DUP!)* Duplicate and Damaged Packets

so ... after this ping command u not receive other error
so for fix this error u need to add exception => every timeout error do : ping 5 times or 8 times on target address
