Test Case

TC-SC-4.3

Reproduction steps

Command used to launch the DUT : ./lit-icd-app
Command used to run the python script : python3 TC_SC_4_3.py --commissioning-method on-network --discriminator 3840 --passcode 20202021 --storage-path admin_storage.json

While validating the TC-SC-4.3 python script, Test case is failing at test step 10 TH performs a DNS-SD browse for _I<hhhh>._sub._matter._tcp.local, where <hhhh> is the 64-bit compressed Fabric identifier, expressed as a fixed-length, sixteen-character hexadecimal string, encoded as ASCII (UTF-8) text using capital letters. with the below errors.
