SOLVED [LAN] launch a game without internet : Error with auth server

[zebu14]

Hello, I am trying to start a new headless server game (on a fresh install of headless 0.17.79) hosted on a LAN (without internet access)

I have set :
"visibility":"lan",
and
"_comment_require_user_verification": "When set to true, the server will only allow clients that have a valid Factorio.com account",
"require_user_verification": false,

In the server_settings.json file

I am using the following cmd to start the game :
/opt/glibc-2.18/lib/ld-2.18.so /images/factorio/bin/x64/factorio --executable-path /images/factorio/bin/x64/factorio --server-settings /images/factorio/data/server-settings.json --start-server /images/factorio/test.zip

(my glibc is installed into /opt/ and factorio into /images/)

I obtain :
5.135 Factorio initialised
5.135 Info HttpSharedState.cpp:54: Downloading https://auth.factorio.com/api-login?api_version=2
5.148 Error HttpSharedState.cpp:136: CURL failed: code:6, 6; Could not resolve host: auth.factorio.com
5.148 Info HttpSharedState.cpp:145: Downloading https://auth.factorio.com/api-login?api_version=2

5.198 Goodbye
0.000 Error Util.cpp:83: Couldn't parse the response from the auth server. This seems to be an internal server error.

As if the server-settings.json was ignored ....

Have I missed something ?

Thank you

Hello,

I have finally found how to start the headless server withou auth check

I had my credentials still present in the server-settings.json files :
"_comment_credentials": "Your factorio.com login credentials. Required for games with visibility public",
"username": "hello",
"password": "######",

"_comment_token": "Authentication token. May be used instead of 'password' above.",
"token": "#########################",

I removed the password and the token and now it's ok.

If it can help someone with the same behavior ==> Be sure to have nothing filled in "password" and "token" fields.
