I am trying to set up a spigot server off a spare laptop that I have converted to ubuntu, but for whatever reason I get the error in the title when I try to connect off my Windows 10 PC. Here are logs of the errors: Spoiler: Error 1. [13:00:06] [User Authenticator #1/INFO]: Disconnecting [email protected][id=,name=USER,properties={},legacy=false] (/192.168.0.20:60735): Authentication servers are down. Please try again later, sorry! [13:00:06] [User Authenticator #1/ERROR]: Couldn't verify username because servers are unavailable [13:00:06] [Server thread/INFO]: [email protected][id=,name=USER,properties={},legacy=false] (/192.168.0.20:60735) lost connection: Authentication servers are down. Please try again later, sorry! Username redacted as USER. Spoiler: Error from friends. io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: I have tried updating certificates, I have opened all ports (I don't think my ISP lets me but I am connecting over LAN so it shouldn't matter. Another detail, if I set the server to offline mode, it allows me to join. No I am not using a cracked account. Time zones on both computers are set to my local, to no avail. server-ip is blank, I've tried with internal and external IP's just messing around. EDIT: Do I need a specific version of java installed? UPDATE: I configured an IP Passthrough, so no ports should be closed, however the same error occurs.
