2024-01-25 12:18:07 [WARNING] [Instrument] dvt.py[line:248] socket connection close The connection was closed before it was started. Have you tested any other commands?

[antuking]

As you say, the connection was closed before the command started. I tried to perform other commands and give the same error. What should I do? Restarting all ios devices (v16.x), or do something else

[YueChen-C]

I seem to have encountered the same problem before. Frequent creation of DTServiceHub resulted in too many open fds. The solution is to then reboot or reinstall Developer Disk Image

You can only restart the device to delete DDI

Seems that this issue resolved. I tried to perform two ways to reproduce. Both of them works fine for me now. Thank so much more @YueChen-C
