Factorio Forums

My friends and I have been trying to play online, but I can't connect to their server. It gives me the error in the title: Couldn't establish network communication with server. In addition, in the public game browser, I'm unable to ping their server.

I can play on LAN with other groups, and I can see other servers online. Some of them have this issue, though.

I don't know if this is the difference or not, but I am not on Steam and both of the friends I wanted to play with are.

I can connect if I convert my game to Steam. Is there a communication issue between steam and non-steam installs in version 17?

DNS looks like it might be hosed for auth.factorio.com - I've tested the IPs both inside and outside my network and they all fail.
