Problem with Geyser and Floodgate on Velocity Proxy

[limpid dagger]

Hello.
I have a problem with Geyser and Floodgate on my Velocity Proxy.
I installed both two weeks ago and configured it - it worked flawlessly.
But now it doesn't work anymore. I tried re-downloading the plugins, created a completely new velocity instance and tested it with that but it won't work.
I can connect without a problem with Java but Bedrock gives a (not helpening) error screen (picture below this post).
Here is the Geyser-Dump: https://dump.geysermc.org/bpc7J5CdWFM4SDYQqGhTRbHBh8vfGjBa
And here the Server log (debug enabled): https://mclo.gs/9X9tO5k

The log includes the time where I tried to connect to the bedrock server. (but there is no indicator for that in the logs)
Does anyone have an idea why i can't connect?

PS: After it worked I got a new internet-connection with ipv4 & ipv6 (I had no iv6 before). While switching to the new Internet I enabled ipv6 localy in my network aswell. Maybe that can be a problem.

the same error after the update, which @gritty raptor suggested

[torpid flame]

ipv6 might cause issues, try disabling it

[limpid dagger]

I can't, because I use playit.gg and the tunnel needs ipv6 fto route through the hearest datacenter.
But I tried it on my win11 pc and made a hotspot and disabled the ipv6 protocol in my network-adapter settings And ran the backend servers localy. No changes

[torpid flame]

ah, playit

have you configured playit to use 2 tunnels, one for java one for bedrock

[limpid dagger]

I had two tunnels. But since it doesn't Work I only tried to join localy in my network

I used Windows cmd to Check If the Port 19132/UDP ist listening - and it is

[torpid flame]

does joining locally work?

[limpid dagger]

No
Java: yes, but Bedrock not

[torpid flame]

what version of bedrock are you attempting to join with?

[limpid dagger]

Thr Server I entered in Bedrock was 127.0.0.1 Port 19132

[limpid dagger]

The newest that is possible for windows

[torpid flame]

unfortunately uh, versions have been a little messy

some people aren't updated to 1.21.120 correctly

so I'm curious if you're on 1.21.114 or 1.21.120

[limpid dagger]

I also tried "localhost" but since Windows Had Problems with the localhost in recent Updates i used the ip

[torpid flame]

since if you're on 1.21.114, the answer is clear

if you're on 1.21.120, idk

[limpid dagger]

I can't look at this Moment but I will sende the Version shortly

[limpid dagger]

so I should update?
Or what is the answer?

Because there is no update available

[torpid flame]

!!loopback

[torpid flame]

yeah it's a little borked

[limpid dagger]

I installed the update and now it works. Thanks!

[limpid dagger]

I am now hosting the server on an extra PC in my network. From my Windows PC I can now connect after the update to 1.21.120.
But a ps5 player outside of my network can't join. But other players outside of my network can.

What error message do they get?
