ProtocolLib 5.0 is not compatible below Minecraft 1.19, please downgrade.

ProtocolLib 5.0 is not compatible below Minecraft 1.19

I also tried using v4.8.0 but the plugin responds with: "[FastLogin] Setups using Minecraft proxies will start delayed when the command from the proxy is received" and it doesn't autologin players. Sorry if it's a dumb question but how can I fix it?

[TuxCoding]

Please add that log entry. It means it found no session for that player. So it missed the login process. If you use BungeeCord or Velocity, you should follow the setup guide referenced on the main page.

[Server] Server thread/INFO [FastLogin] No on-going login session for player: CraftPlayer{name=imAlejandro04} with ID
[Server] Server thread/INFO [FastLogin] Setups using Minecraft proxies will start delayed when the command from the proxy is received

I'm just using Spigot. Not Velocity or BungeeCord

Now you are using a different FastLogin version. Please keep using 1091 for 1.18.
