I have tried to make a local server. It is seen using the LAN session option, but the black screen with the "connection to... " message appears just à second, then we get the server selection screen.
I have also tried a Linux server outside my LAN. I get the "checksum mismatch. Kicked" error. The steam validation of my files doesn't fix the problem.
