The mini display port to type c didn't work for me, still giving me black screen after 10 seconds

Recently I got a 3070 laptop, it has no DP or mini DP, so I got a adapter type c to DP(4k 60Hz) and when I plugged it in, it would work for like 10 seconds, then turn off and give me the HDCP error, and no headset cable is perfectly fine along with other thing because i used it on my desktop and it works perfectly fine I also made sure that type c is to the dGPU, not the iGPU
