[Bug] Connection Issues with BCLib mod and Velocity Proxy Server #124

Open ThisIsLamer opened 1 year ago

ThisIsLamer commented 1 year ago

What happened?

I've encountered a problem when trying to connect to my Minecraft server via the Velocity proxy server. I have the BCLib mod installed, which is a dependency for another mod that I use. Without this mod, the connection works fine, but as soon as I install it, an error occurs and the connection drops.

The errors I see in the Velocity console point to a problem with packet decoding. Here are snippets from the error logs:

[21:28:07 ERROR]: [server connection] Lamer13 -> survival: exception encountered in com.velocitypowered.proxy.connection.backend.BackendPlaySessionHandler@139a8a9a
com.velocitypowered.proxy.util.except.QuietRuntimeException: A packet did not decode successfully (invalid data). If you are a developer, launch Velocity with -Dvelocity.packet-decode-logging=true to see more.

        at com.velocitypowered.proxy.protocol.packet.brigadier.ArgumentPropertyRegistry.deserialize(ArgumentPropertyRegistry.java:87) ~[velocity.jar:3.2.0-SNAPSHOT (git-37fedf50-b260)]

The Minecraft server logs show the following messages:

[21:28:07] [Server thread/INFO]: Lamer13 joined the game
[21:28:08] [Server thread/INFO]: Lamer13 lost connection: Disconnected
[21:28:08] [Server thread/INFO]: Lamer13 left the game

I am using Fabric as the mod-loader and have installed the FabricProxy-Lite mod on the server for Velocity support.

Any help in resolving this issue would be greatly appreciated. If further information is required, I'd be glad to provide it.

Thank you.

4 months passed, is there a way to solve it?🥲

ThisIsLamer commented 9 months ago

I couldn't find any solution, so I decided to write my own solution that fits my needs.

I created a simple proxy server that stores IP:port pairs and their corresponding domains. My goal was to make it possible to connect to different domain addresses for game servers located on the same physical server. If needed, I can provide a link to the source code.

Thank you, but my friends and I have decided to give up adding these mods to the server😂
