bug report: bzl cannot push build events to remote UI serve

[wondfor]

when I start a server on 10.116.238.96, the command as this:
./bzl serve --grpc_host 10.116.238.96 --grpc_port 1080 --http_host 10.116.238.96 --http_port 8081
and the add
build:bezel --bes_backend=grpc://10.116.238.96:1080 build:bezel --bes_keywords=user=vscodetrial build:bezel --bes_results_url=http://10.116.238.96:8081/invocations build:bezel --bes_timeout=100s build:bezel --build_event_publish_all_actions build --config=bezel
into .bazelrc
then，I run bazel on 7.189.52.164 with the command bazel build //:persistence_sdk，and it success
Target //:persistence_sdk up-to-date: bazel-bin/persistence_sdk.tar.gz (18:03:08) INFO: Elapsed time: 49.112s, Critical Path: 38.67s (18:03:08) INFO: 943 processes: 937 remote cache hit, 5 internal, 1 processwrapper-sandbox.
