Port 10000 closed in Sony Alpha 7R4MA

Question

according to Sony Remote API manual. I can access the internal website of the camera.

http://192.168.122.1:64321/dd.xml

From there I can get to: http://192.168.122.1:64321/DmsDesc.xml

and to: http://192.168.122.1:64321/DigitalImagingDesc.xml

And in the end to: http://192.168.122.1:64321/DmsRmtDesc.xml

There is an information whrere to send JSON POST request

<av:X_ScalarWebAPI_ServiceType>camera</av:X_ScalarWebAPI_ServiceType> <av:X_ScalarWebAPI_ActionList_URL><av:X_ScalarWebAPI_ServiceType>camera</av:X_ScalarWebAPI_ServiceType> <av:X_ScalarWebAPI_ActionList_URL>http://192.168.122.1:10000/sony</av:X_ScalarWebAPI_ActionList_URL></av:X_ScalarWebAPI_ActionList_URL>

for example:

curl -v -H "Content-Type: application/json" -X POST -d '{ "method": "getAvailableApiList", "params": [], "id": 1, "version": "1.0" }' http://192.168.122.1:10000/sony/camera Note: Unnecessary use of -X or --request, POST is already inferred.

Scan of that port by nmap:

sudo nmap 192.168.122.1 -p 10000 Starting Nmap 7.80 ( https://nmap.org ) at 2024-03-09 14:52 CET Nmap scan report for 192.168.122.1 Host is up (0.018s latency). PORT STATE SERVICE 10000/tcp closed snet-sensor-mgmt Nmap done: 1 IP address (1 host up) scanned in 1.29 seconds

Any ports?
