I also encountered this issue with AntiPopup 5.3 with:

• Velocity 3.2.0-SNAPSHOT (git-f744b37a-b222)
• Purpur git-Purpur-1888 (MC: 1.19.3)*

It happens from time to time, and only occurred when joining the server. If this happens, the player simply gets force disconnected from the server.

This is my pl list

@Akiranya what's your plugin list too?

It's pretty weird that "packet_handler" is not existent?

Check your protocollib version, if its outdated update it.

Hi, it's the latest dev build

ProtocolLib version 5.0.0-SNAPSHOT-b612

Just curious... doesn't AntiPopup already shade packetevents?

it does yes

I uninstalled Antipopup but I also triggered this issue. It happens when the player tries to join while the server is still starting and before the server console prints Done!. After the server prints Done!, the server lets the player join, and then this error occasionally happens - player just get disconnected

It looks like AntiPopup just happens to be presented in the call stack since it listens to the PlayerJoinEvent

So, this may not be an issue with AntiPopup but I really wanted to fix it. Do you have any clue? I have no idea how these network packets work..

If that's the case join my discord and send your server log without my plugin present. I'll try to help you.

@rafalohaki can you try without my plugin too?

i cant remove it if its installed already, right? i have players and cant restart map.
its not so bad, its rare but not so serious.

Yeah to remove you'd need a restart

After a few days of testing, I found it's still the issue with AntiPopup... the problem occurs quite often if I have AntiPopup installed

I was not using Antipopup 5.4 RC1 tho, not sure if the latest version could fix this issue

I suggest using 5.2 if 5.3 appears to be problematic.
