"Your connection to limbo encountered a problem."

[LeonBoettcher]

I have a Problem when using Pico Limbo, it kicks me after less than 1min with the Message "Your connection to limbo encountered a problem."

Output PicoLimbo using # Trace-level logging (most verbose) pico_limbo -vv

I will need more details:

• Are you getting any logs on the client? Like in the crash-reports directory of your game?
• What's your client version?
• Any mods on the client? (other than Sodium or Optifine and similar)
• Any plugins on the Velocity proxy such as ViaVersion?
• What's the configuration of PicoLimbo?

Are you getting any logs on the client? Like in the crash-reports directory of your game?

No Crash logs, the only thing i can give you is my client log, i connected 2 times to the limbo the first time, connecting to papermc survival and then switching to limbo. The 2nd time directly connecting to limbo. https://pastebin.com/zkBw3Xr7

What's your client version?

1.21.10

Any mods on the client? (other than Sodium or Optifine and similar)

Iam using Vanilla 1.21.10 for testing

Any plugins on the Velocity proxy such as ViaVersion?

Does limboapi support 1.21.10? It doesn’t seem like it, given that it was last updated four months ago.
I am seeing this warning when starting the proxy with the plugin:

[14:54:22 WARN] [limboapi]: Current LimboAPI version doesn't support current Velocity version (protocol version numbers: supported - 772, velocity - 773)
[14:54:22 WARN] [limboapi]: Please update LimboAPI (https://github.com/Elytrium/LimboAPI/releases). LimboAPI support: https://ely.su/discord

I tried limboapi in 1.21.10 with nanolimbo whitch worked, but that doesnt mean it has to work with PicoLimbo. I´ll wait for a Update of LimboAPI and see if it fixes the issue.

As I read threw your Docs again, i saw that i dont need LimboAPI for your Limbo System right?
I tried disabling the plugin and using the Limbo, i can join it and it works as with the plugin, but the same disconnecting issue is still there.

Unfortunately I was unable to reproduce the issue you're encountering on my end.
If you'd like to share more details, I can try again.

I don't know what features LimboAPI brings, but PicoLimbo does not absolutely require a plugin to function.
