QCoDeS: ConnectionResetError [WinError 10054] When Controlling Magnet Power Supply in Oxford Triton

[johnnyzhaophysics]

I am encountering a recurring ConnectionResetError ([WinError 10054] An existing connection was forcibly closed by the remote host) while controlling the magnet power supply of an Oxford Instruments Triton dilution refrigerator using QCoDeS. The error occurs when sending commands to set the magnetic field. Below is the traceback of the error.

An exception occurred in measurement with guid: 426b9388-0000-0000-0000-0195a603c9c9;
Traceback:

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

Despite efforts in increasing the timeout and restarting the computer, the error persists. I would like assistance in understanding why the connection is being reset and how to prevent this issue from occurring. Any advice on troubleshooting or potential solutions would be greatly appreciated.

@johnnyzhaophysics I assume this is the same issue as #6975 ?
