I have no idea what the problem is, I've done a lot of searching and even went through old issue reports here to find some lead. I have bungee hooks enabled in AuthMeReloaded.
I am running AuthmeReloaded 5.6.0-SNAPSHOT on my 1.14 server, and 5.4.0 release on all the other servers.
On my BungeeCord (v Waterfall-Bootstrap:1.14-SNAPSHOT:1f16030:286) instance, I'm running AuthMeBungee 2.2.0-beta1, BungeeChat 2.1.6.855, BungeePing 2.0, BungeeTabListPlus 2.8.10, HubMagic 0.2.6, NuVotifier 2.5.3, and SkinsRestorer 13.6.1. I can give you any logs you need, but where do I start? I've looked through everything I could think was related, and ALL of the 9 servers are having this problem. I have to remove plugin this until the issue is resolved. I only need this to add the FastLogin plugin.
Another note: In Authme 5.4.0, it is no longer hooks.bungeecord in authme's configuration. It is now this and your instructions on your Spigot page still say the old one. Perhaps this is my problem and I'm overlooking something, but the text seems clear.
