多台设备，USB没问题，Wifi就会随机几台设备出现adbutils.errors.AdbError: unknown host service

连了8台手机，型号一样，都是小米Note 11。用USB连接的时候可以正常工作，不会报Bug。但是用Wifi连接的时候，差不多一旦超过3台设备，就会出问题。本次出现的具体问题不一样，但最终一般都落到了这个问题上： adbutils.errors.AdbError: unknown host service 我在想，是因为网络不如USB稳定，所以Axagent 不能及时返回操作结果，然后再ADB就会出问题吗？求教！

手机型号多台小米Note 11
