Cómo detectar un error: conecte ECONNREFUSED en TCPConnectWrap.afterConnect [como oncomplete]

Estoy usando @nestjs/axios en mi aplicación de back-end NestJS para llamar a un punto final como se muestra a continuación:

 this.httpService.get('some url').pipe( catchError(e => { throw new InternalServerErrorException('error'); }), map(res => { console.log('succeeded'); }) );

El problema es que cuando el punto final está disponible, se alcanzará el succeeded , pero cuando el punto final no está disponible, el catchError nunca se alcanza y tampoco se succeeded .
