Origins Legacy is not detected when connecting through Velocity + FabricProxy-Lite (works with direct connection)

[ainer0ff]

Version information

1.12.8+1.21.11

Minecraft Version

1.21.11

Expected Behavior

join server

Actual Behavior

Origins Legacy is not detecting the client mod when connecting through a Velocity proxy with FabricProxy-Lite.

Direct connection to the Fabric server works correctly, and the client is detected as having Origins Legacy installed. However, when connecting through Velocity (Paper lobby → Fabric backend), Origins Legacy thinks the client does not have the mod installed and disconnects the player

Reproduction Steps

Download FabricProxy-Lite and Origins Legacy, install them on your server, and connect them to velocity

Java Provider + Version

JAVA_21

Log file

latest.log

Oh god this is a rough one, it's largely due to how Origins does its network detection.
As a workaround for now, you can turn off the performVersionCheck config for Origins.

[ainer0ff]

thanks I'll check it out, but there's a new problem. I tried to log in to the server without velocity, and I got a new error

It looks like for whatever reason PacketEvents is unable to get Origins: Legacy's registry entries? Legacy is using the Vanilla MC way of doing things, are you sure this isn't on them?

Sorry, I don't know English, and the translator is giving me weird results. I just wanted to log in to the server, but I'm getting an error.

[BluSpring]

The PacketEvents mod seems to be causing problems, I'm pretty sure.

[ainer0ff]

I get it now; it's just that this problem didn't exist before.

[BluSpring]

I don't know why it's existing now and Origins isn't doing anything weird for this specific aspect, so I have no idea.

[ainer0ff]

Well, if I remember correctly, the client log said there were about 300,000 entities or objects. I tried deleting the world, but it didn't help.

[BluSpring]

do you mind sending that log?

[ainer0ff]

Okay, but it'll be a couple of hours from now—it's already nighttime here, and I've already turned off my computer.

[BluSpring]

I don't know what's going on here but I really don't think this is Origins Legacy's fault
Maybe it'll be fixed in the rewrite, but that's going to take a while... hm.

[ainer0ff]

How to solve this problem? don't you know?

[BluSpring]

I do not, I genuinely have no clue what is failing here.

[ainer0ff]

I tried to delete all the libraries and so on, and now I'm getting a slightly different error.

could it be because of flectonepulse?
it was just a similar problem that didn't let me in and it was because of it
