first record does not look like a TLS handshake

[zzozzolev]

문제

• grpcurl로 insecure port를 호출하니 아래와 같은 에러 발생

  $ grpcurl localhost:50051 list
  Failed to dial target host "localhost:50051": tls: first record does not look like a TLS handshake

해결

• -plaintext 옵션 추가

  $ grpcurl -plaintext localhost:50051 list
