Will not let players join server in a Velocity network

[Baktus79]

General Information Server version: 1.17.1 Server software: Paper Client version: 1.18.1 Client software: Vanilla Plugin version: 2.4.4

Describe the bug I recently switched proxy server from Waterfall to Velocity, but it seems that ClientDetector does not like Velocity. With ClientDetector on Paper, all players will be hanging on "Joining world".

The server works just fine when I remove ClientDetector. I have also made sure that crossServerNotifications is set to false.

Hi there,

1. your config.yml is not up to date, can you regenerate it (delete the file, reload the server).
2. I will take a better look at your problem when I'm back from school. ~Sportkanone123

Hi and thanks for the response.

I deleted the entire ClientDetector folder and reloaded the server, but still the same problem.

[Sportkanone123]

I am able to reproduce your problem, I am now working on analyzing and fixing the problem. ~Sportkanone123

[Sportkanone123]

Hey, sorry that it took so long, but now it should be fixed now. New version will be released on SpigotMC soon. ~Sportkanone123

[Sportkanone123]

Fixed, see: https://www.spigotmc.org/resources/clientdetector-client-mod-detection-forge-mod-detection-clientcontrol.90375/update?update=443300

Perfect! Thanks very much for your work :)
