No logfies send to syslog-server

Hallo,
I try to use syslog to collect my logfiles:
I configured a server using the options under tools/loging.
The problem:
Rancher 20 doesn t send any informations allthough the level is set to debug. The syslog-server is reachable, tested with telnet.
Can anyone give me hint?

Thanks

Ralf
