I want to setup graylogs in my service.
I installed the docker image.
And I also set input for 'GELF UDP'
the configuration is,
Bind address: 0.0.0.0
Port: 1514

and when i click 'Start input' it show error.

the error log shows,
2024-05-10 07:18:58,409 WARN : org.graylog2.shared.rest.resources.ProxiedResource - Failed to call API on node , cause: null (duration: 4 ms)

how can i do?
