리눅스에서 Veraport 핸들러가 동작하지 않아요

리눅스에서 잘 빌드되고 각 핸들러 스레드가 뜨는데 정상 동작하지 않습니다.
일단 확인한 은행, 핸들러는 하나은행, Veraport 인데, Ubuntu 17.04 Chrome, Firefox 모두

라면서 보안 프로그램 설치 페이지로 redirect 되더니 통합설치프로그램 Veraport 미설치가 뜹니다.

여기서부터 Chrome, Firefox 동작이 갈리는데요,

Chrome은 다음과 같은 로그를 내고,
```
[03:29:16] [VeraportHandler] GET /

Exception thrown: 'System.Collections.Async.AsyncEnumerationCanceledException' in AsyncEnumerable.dll
Exception thrown: 'System.Threading.Tasks.TaskCanceledException' in System.Private.CoreLib.ni.dll
```

Firefox는 다음과 같은 로그를 냅니다.
```
Exception thrown: 'System.IO.IOException' in System.Private.CoreLib.ni.dll
