16.1 Could not acquire a valid license for Intel FPGA SDK for OpenCL

Hello everyone, I encountered a problem installing the Opencl FPGA SDK. I downloaded the 16.1 version and downloaded the corresponding 16.1BSP. After installing QUARTUS, I used a newly registered license and software identification was available. After that I tested the "aocl diagnose" command without any problem. But when I tested the compilation instructions and compiled the vector_add project, the problem appeared. The problem says I don't have a valid license for opencl fpga sdk, but I do. My operating system is centos7（BSP recommanded） and my board is DE5A-NET-E1. Do I still need a license? I've been stuck here for a long time, please ask for advice. Thank you
