This only can happen on RM have multiple IPs, related code is inside AmIpFilter.java doFilter function:

    if (!getProxyAddresses().contains(httpReq.getRemoteAddr())) {
      String redirectUrl = findRedirectUrl();
      String target = redirectUrl + httpReq.getRequestURI();
      ProxyUtils.sendRedirect(httpReq,  httpResp,  target);
      return;
    }
