我正在尝试使用Android测试站。我下载了Android测试站CLI并运行./mtt start，但UI没有启动。然后我运行docker exec -it mtt cat /data/log/server/current以获取docker之外的日志。这是日志

云数据存储模拟器似乎返回503"服务不可用"。但我确信Cloud Datastore Emulator是通过top命令运行的。
在python脚本中添加一些日志，我得到了启动Cloud Datastore Emulator的命令，它是
'/usr/lib/google-cloud-sdk/platform/cloud-datastore-emulator/cloud_datastore_emulator', 'start', '--testing', '--regenerate_indexes=false', '--auto_id_policy=SCATTERED', '--port=8007', '--store_on_disk=true', '--store_index_configuration_on_disk=true', '--index_file=/mtt/index.yaml', '--storage_file=/tmp/mtt/datastore.db', '--require_indexes', '/tmp/tmpwvDVWT'。
这个命令有什么问题吗？有人能告诉我们为什么会出现503错误吗？
更新：
我找到了原因。我在.doker/config.json中添加了no_proxy设置，它就工作了！如果您有类似的问题，只需将noProxy设置为"；localhost，127.0.0.1，metadata.google.internal"将解决它。
