끄투 서버 열기 질문

PGAdmin 4, postgre v.16, Node js v.20 입니다.
끄투 서버를 열려고 했는데, DB까지 연동 했는데

node:events:492 throw er; // Unhandled 'error' event ^ Error: bind EACCES null:80 at listenOnPrimaryHandle (node:net:1940:18) at rr (node:internal/cluster/child:163:12) at Worker.&lt;anonymous> (node:internal/cluster/child:113:7) at process.onInternalMessage (node:internal/cluster/utils:49:5) at process.emit (node:events:526:35) at emit (node:internal/child_process:951:14) at process.processTicksAndRejections (node:internal/process/task_queues:83:21) Emitted 'error' event on Server instance at: at listenOnPrimaryHandle (node:net:1941:21) at rr (node:internal/cluster/child:163:12) [... lines matching original stack trace ...] at process.processTicksAndRejections (node:internal/process/task_queues:83:21) { errno: -4092, code: 'EACCES', syscall: 'bind', address: null, port: 80 } Node.js v20.10.0 ```
이렇게 오류가 뜹니다.

코드 수정한거 없고, DB, inc.json 파일 json으로 고친것만 해놓았습니다.
