httprobe is missing valid HTTP services

[MMquant]

httprobe doesn't discover live valid HTTP services.

It doesn't output HTTP services which return

curl: (56) OpenSSL SSL_read: Connection reset by peer, errno 104

Consider following curl request

$ curl -kiv https://xxx.xxx.xxx.xxx:443
*   Trying xxx.xxx.xxx.xxx:443...
* Connected to xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx) port 443 (#0)
...
...
* SSL connection using TLSv1.3 / TLS_AES_128_GCM_SHA256
...
...
> GET / HTTP/1.1
> Host: xxx.xxx.xxx.xxx
> User-Agent: curl/7.81.0
> Accept: */*
> 
* OpenSSL SSL_read: Connection reset by peer, errno 104
* Closing connection 0
* TLSv1.2 (OUT), TLS header, Supplemental data (23):
curl: (56) OpenSSL SSL_read: Connection reset by peer, errno 104

This is live valid HTTP service and actual behaviour of F5 reverse proxies.

The F5 returns a 200 if a valid existing virtual host is passed in the request

$ curl -kiv https://xxx.xxx.xxx.xxx -H 'Host: int-account.xxx.com'
*   Trying xxx.xxx.xxx.xxx:443...
* Connected to xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx) port 443 (#0)
...
...
* SSL connection using TLSv1.3 / TLS_AES_128_GCM_SHA256
...
...
> GET / HTTP/1.1
> Host: int-account.xxx.com
> User-Agent: curl/7.81.0
> Accept: */*
> 
* TLSv1.2 (IN), TLS header, Supplemental data (23):

If I httprobe the xxx.xxx.xxx.xxx:443 the service it's not marked as a valid live HTTP service

$ echo 'xxx.xxx.xxx.xxx:443' | httprobe 
$
