Bug Report: Connection reset instead of kick message

[TianmuTNT]

General information

First, I'm not entirely sure if this is a bug, so I apologize if I'm bothering you

The main issue is that after verification is completed, it doesn't properly return the message "Please rejoin," but instead returns "connection reset"

Multiple players have experienced similar issues (but they can rejoin the server)

The issue occurs on both Bukkit and Velocity. Below is my config.yml file.

config.yml

If you need me to provide anything else, please feel free to contact me—I'm happy to help anytime! Also, my English isn't very good, so I apologize if anything is unclear.

Steps to reproduce

I'm not sure if this issue can be reproduced in your environment, but here are the steps:

1. Set up a server with Sonar installed (either Bukkit or Velocity).

2. Join the server.

3. Complete the Sonar verification.

4. The connection gets reset or lost.

Do you have client logs? If so, please upload them to https://mclo.gs/.

Additionally, are you using some kind of reverse proxy?

[jonesdevelopment]

By the way, you can also use the transfer feature to skip the kick altogether. I think that'd be the cleanest solution for now.

I did not use any reverse proxy

If I understand correctly, this configuration requires the server address, right? If that's the case, then it might not be very helpful for me, because when I use the transfer feature, it still results in a "connection reset" once.

I need to clarify something: this issue doesn't happen every time—it only occurs occasionally. I'm not sure what triggers it.

What do you mean by that? You need to enter the information you use to connect to the server.
If you join using myserver.xyz:25555 you have to enter myserver.xyz and 25555 in the config.

It looks like you're using modded Minecraft. Has this ever happened without any mods (vanilla Minecraft)?

i will try

Well, that should simply not happen. Maybe your network firewall drops the connection for some reason...
