failed to destroy rule externalIP to clusterIP {"error": "exit status 2"}

안녕하세요. RKE2 기반의 쿠버네티스 배포판을 온프레미스 환경에서 운영 중입니다.
yatai라고 하고 BentoML 모델을 쿠버네티스에 쉽게 배포해주는 오픈소스를 쓰는 와중에 100MB 정도되는 모델을 yatai에 올릴려고 하니까 40~50MB 정도 업로드 되었을 때 항상 connection reset by peer에러가 발생했고, 검색하다 보니 감사하게도 공유해주신 이 오픈소스를 찾게 되었습니다.

그런데

Enable Drop Invalid Packet Rule in INPUT chain 옵션은 true,
Enable External-IP to Cluster-IP DNAT Rule 옵션은 false

으로 설치하고 설정했을 때 모든 Pod들에서 Crashloopbackoff 에러가 발생하고 있습니다.
env 설정 값은 정상적으로 들어간 것 같습니다.
혹시 어디서부터 손대면 좋을지 조언을 여쭤볼 수 있을까요?
