This problem has existed since version 15.1.
Please check the relevant part of the code to see if the setting of the specified port is omitted.
The speculation is based on the analysis of log files, and it should be easy to reproduce the fault.
My previous solution to this problem was to install version 15.1. However, the 15.1 version cannot be installed now, and the hcmon license it contains has expired.
Please check it, thank you.
