Error - Fail to connect - Server - OpenRCT2 - Debian 10

[Yannik_23]

Hi, 

now I installed OpenRCT2 on Debian 10:

When I start a server with the following command, then there comes an error-message:

---------------------------------------------------------

openrct2@2f21c4ac-26ca-4ba7-8d15-270032ef22df:~$ openrct2 host savefile.sv6 --headless
ERROR[/root/OpenRCT2/src/openrct2/network/Socket.cpp:261 (Listen)]: IPV6_V6ONLY failed. 92
Ready for clients...
openrct2 $ WARNING[/root/OpenRCT2/src/openrct2/network/Socket.cpp:785 (CreateSocket)]: IPV6_V6ONLY failed. 92

---------------------------------------------------------

 

When I try to join:

---------------------------------------------------------

openrct2 $ ERROR[/root/OpenRCT2/src/openrct2/network/Network.cpp:2814 (Server_Handle_AUTH)]: Unknown failure (3) while authenticating client

---------------------------------------------------------

-> client message: "Connection closed"

 

 

Please help.

The problem was the client-version. It wasn't the development build.
