I'm not sure if this is a spigot issue, an AutoSaveWorld issue, or a PEX issue. I am using MySQL backend so I don't know how to provide a permissions file, I will follow any instructions given. I'll get to the point: Command1: /pex user malon group set zeus console says: [18:33:49 INFO]: malon issued server command: /pex user malon group set zeus nothing more and the command succeeds. Command2: /pex user Nic82 group set hermesfollower (you can replace this with any command, pex is unable to manage this player.../pex reload, /pex user delete, etc) console says: [18:33:41 INFO]: malon issued server command: /pex user Nic82 group set hermesfollower [18:33:41 WARN]: [AutoSaveWorld] Plugin PermissionsEx attempted to establish connection socket://api.mojang.com:443 in main server thread and the user is not modified. Relevant Server Info: AutoSaveWorld 4.14.2 [PermissionsEx] version [1.23.2] [18:44:47 INFO]: This server is running CraftBukkit version git-Spigot-870264a-0a645a2 (MC: 1.8.3) (Implementing API version 1.8.3-R0.1-SNAPSHOT) Oracle Java 8u45x64 for Ubuntu 14.04LTS x64 (ppa:webupd8team/java) Where can I look for a more detailed message? I have tried running the server as root and as a user, no difference. Thank you!
