Users failing to connect to server properly

We use a Waterfall proxy connecting to several Purpur servers. A handful of users consistently fail to properly log onto the server, generally regardless of current server traffic, while being able to connect to other servers and while others can connect to our server. What's the best place to start looking into it? I've attached an example screenshot and a list of plugins on the proxy.

console seems to output this message, while the server itself is still up and running (and the player locally still is in the game world, but unable to interact with anything)

one set alternate keep-alive to true in purpur.yml (for the placebo effect), i would ask ur users who have issues to do a winmtr to ur server to check for packet loss etc are ur backends network-compression set to -1? and it probably wont show anything but do a /spark profiler start --timeout 600 --threads *

alternate keep-alive is on and didn't fix anything, user sent following winmtr (I don't know my way around them) |------------------------------------------------------------------------------------------| | WinMTR statistics | | Host - % | Sent | Recv | Best | Avrg | Wrst | Last | |------------------------------------------------|------|------|------|------|------|------| | 192.168.0.1 - 0 | 21 | 21 | 0 | 0 | 10 | 0 | | meo.Home - 0 | 21 | 21 | 0 | 1 | 10 | 0 | | No response from host - 100 | 4 | 0 | 0 | 0 | 0 | 0 | | telepac13-hsi.cprm.net - 75 | 4 | 1 | 0 | 31 | 31 | 31 | | lis1-cr1-be10-200.cprm.net - 0 | 21 | 21 | 15 | 17 | 33 | 16 | | e0-33.core2.lis1.he.net - 60 | 5 | 2 | 0 | 19 | 22 | 17 | | No response from host - 100 | 4 | 0 | 0 | 0 | 0 | 0 | | port-channel1.core1.orf2.he.net - 43 | 7 | 4 | 91 | 92 | 93 | 91 | | port-channel15.core2.mia1.he.net - 60 | 5 | 2 | 0 | 113 | 114 | 112 | | No response from host - 100 | 4 | 0 | 0 | 0 | 0 | 0 | | play.stoneworks.gg - 20 | 10 | 8 | 254 | 259 | 264 | 260 | |||||||__| yes

These are not magic values. Many of these settings have real consequences on your server's mechanics. See this guide for detailed information on the functionality of each setting.

❌ Outdated

You are using Pufferfish-72 (1.18.2). Update to 1.20.1.

❌ Aikar's Flags

Use Aikar's flags.

❌ mobs.villager.brain-ticks

Increase this in purpur.yml. Recommended: 4.

❌ mobs.villager.spawn-iron-golem.radius

Increase this in purpur.yml. Recommended: 5.

@ProGamingDK do you have any other advice toward this or a different resource to ask in, or should I just cope?
