Bug Description

First of all, I've submit a issue in the reverse proxy's repo : https://github.com/fatedier/frp/issues/4501 And I've test that the reverse proxy works(because other webscoket server works behind the reverse proxy, only hbbr and hbbs).

Behavior

I can connect to the client only if my computer/client/reverse proxy are in the same network no matter whether the direct-peering is enabled(disable the direct-peering seems taking no effect, wireshark shows it still connecting through private network ip rather than reverse proxy's server ip).
Before I test disabling direct-peering, I can connect to the client if the client and the reverse proxy are in the same network, and my computer doesn't have to be. But after I tested it, no matter whether I disable the direct-peering, I'm stuck at the behavior of step1(both my computer/client/reverse proxy must inside the same network).

How to Reproduce

Deploy the reverse proxy(frp) and the rustdesk server
Test the connection inside the same network (will success)
Test the connection in different network(will failed, controlling side is in a different network than controlled side and reverse proxy)

Expected Behavior

I can connect to the controlled client using the reverse proxy (Of course I mean controlling client is in a different network than the controlled client)

Operating system(s) on local side and remote side

Ubuntu 24.04 with Docker Engine V27.0.3

RustDesk Version(s) on local side and remote side

1.1.12(Server) -> 1.3.1(Client)

Screenshots

Rustdesk connection timeout(Stuck at connecting for a long time and then turns into an error: Timeout)

Wireshark packages if controlling client is in the same network as the controlled client(no matter direct-peering is enabled, keep using the private ip and Success)

Wireshark packages if controlling client is not in the same network as the controlled client(Failed)
