Can't generate the trace or topology graph

[alloevil]

My service runs in the docker container, and the dir looks like above, i add the agent config
"-javaagent:/home/work/skywalking-agent.jar","-Dskywalking.agent.service_name=mqs-device-unreleased-preview","-Dskywalking.collector.backend_service=10.38.163.209:11800",
i checked the ui and there is no endpoints and topology like below

Do you deploy this on docker env? Make sure you Time Zone correct.

[alloevil]

My service runs on docker env and the skywalking backend service runs on the physical server.
The time zone are the correct.
This is the tz of my service runs on docker env below.

This is the tz of the skywalking backend service runs on physical server below.

And the java version is
openjdk version "1.8.0_202" OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_202-b08) OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.202-b08, mixed mode)
