Sometimes, when a player has a weird connection, they are kicked to the fallback server without properly joining it, which causes an error on proxy, as well as some random message on the backend server.

Upon asking, I was told that this error is caused by the client being stuck in the configuration phase, because the proxy did not receive any packets from the client.

Happened on Velocity 359 with no resource pack.

Backend message:

This time, the error on velocity is gone (1h40m uptime), however, the glitched backend message stays, since the user never actually joined it.

Velocity 362, no resource pack

Update:

One dude actually managed to trigger the error even on the Velocity 362 (no resource pack).

Unfortunately, the bug still happens even on the latest velocity version.

Unknown if this related but when I try and join a server while already having been on a server before I now get a "An internal error occurred in your connection." This happening during the Config Phase as I never see the server before disconnected and am in the dirt screen for awhile.

There are no errors in the logs.
I am on latest: Velocity 3.3.0-SNAPSHOT (git-74c932e5-b363)

I have ran build 358 (the build before 359 which in the original post was said to have this issue) for a few months. During that, I never saw this issue.
However, yesterday I upgraded to build 385, after which I started having this issue with random disconnects.
Based on this information, I would suspect this has something to do with commit ecf936f which was the only change between build 358 and 359.
There could also be other changes (mods) that could have influenced this yesterday, so please do not consider this a scientific experiment.

Probably related to #1326, which should have addressed that, but it got removed again in #1371

After reverting some parts of #1371, it seems to be fixed, at least on our server. Also #1326 did not address PluginMessagePacket (where also packets are getting lost).

#1279 might be related?

So the issue is player connecting to 2 backend at the same time? If so how could that even occur?

Also shouldn't velocity drop everything and only handle latest connection? Trying to think of what end result of 2 player connect to 2 backends would look like...

Have a snippet or something of the short that indicates what reversion fixes the issue?

Sure #1459
this fixed the issue at least for our server.

There is also the problem that server is switched, the client has to re-enter the config phase, but sometimes just doesn't respond with a FinishedUpdatePacket. (and it might be a Minecraft client bug, because I tried everything, but because of the nature of the bug I couldn't get a packet log from the clients view)

If the server has the same data packs, features, etc. enabled the client doesn't have to enter the config phase, which improves load times and also just removes this point of error (and the unsecure chat popup also doesn't appear after every switch)

At least that completely solved the issue for our server.

We have random disconnects like this without any datapacks, occurring on server switch.
