下图是macaca Server报错

设备也是有权限的
root@a6e008204b51:~/boss-script# adb devices
List of devices attached
10.91.45.43:15109 device

手动运行 /opt/android-sdk-linux/platform-tools/adb -s 10.91.45.43:15109 forward tcp:9001 tcp:9001 该命令是不会报错的

但是只要使用代码运行就会报错

Start with the Macaca Server path that invokes `/opt/android-sdk-linux/platform-tools/adb` and compare it with the working `adb -s 10.91.45.43:15109 forward tcp:9001 tcp:9001` command. Reproduce the unauthorized error in the macaca-android-docker environment and trace the difference; done means the cause is identified and the code no longer rejects this authorized device.
