• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I provided the complete config and logs, rather than just providing the truncated parts based on my own judgment.

Description

judging by the logs, it seems as if xray is trying to connect to the hysteria server via tcp, while hysteria is udp (quic)? might be something else

Reproduction Method

1. set up a hysteria outbound like below
2. try doing some request through the proxy

nvm it works fine i just failed to build the correct outbound configuration

fwiw it should look like this, since there aren't really any examples out there:
