Bug Description

Hi,
I try to connect to a system hosted by an external party, so I don't have so much information of their system.
I just now, there is the webside I can reach from my linux system with wget or curl and this webside is hosted on a kubernet.
With wget https://webside.domain I get the content, but my frp tunnel ends in a "default backend - 404".
It seems that the forwarded request by the tunnel is not recognized by the hostsystem.

Do you guys have any ideas what parameter I can use to manipulate this request correctly.
Or any other steps I could try?

I would say it is a problem of the webside host, but it works for not frp-tunnel-request and I do not really understand why.

Thank you a lot.

You should set correct host header.
