Possible reasons are 1) Client IP address contacting Mojang and server during server join were different (Do you use a reverse proxy? -> Enable IP forwarding, or disable the feature in the config). 2) Player is offline, but tried to bypass the authentication 3) Client uses an outdated username for connecting (Fix: Restart client)

EDIT: Discard my message with 127.0.0.1 if you used it with local testing.

Please post the complete startup log.

Hi, here are the full startup logs, I connected thru local and playit. https://hastebin.com/share/rupuhenoku.makefile

But when I disable it and set prevent-proxy to true, this happens instead. https://hastebin.com/share/xonamorame.ruby

Any updates?

[Clyde6790pGIT]

Using it on Velocity just times the premium user out.

What message do you get on the client?

What message do you get on the client?

Sometimes it shows either "Timed out" or it says "Authentication servers are currently unreachable." or "Invalid Session"

[Clyde6790pGIT]

Seems like reformatting the device the server was on fixed it, maybe a corrupted host file?
