Please perform the following actions on your frps server machine:

Edit frps.toml: Change log.level = "warn" to log.level = "info".
Restart frps.
Check the frps logs (at /home/data/service/frp/frps.log): Look for messages confirming it's listening on UDP port 7000 for QUIC.
Run netstat:
Linux: sudo netstat -lunp | grep 7000
Windows: netstat -ano | findstr ":7000" (and verify the PID belongs to frps)
Let me know what you find, especially the output of netstat and any relevant lines from the frps log.

我也是相同版本，tcp和kcp均可以连接成功，但是quic不行，也通过netstat和nc确认了frps确实在监听quic的UDP端口，切可以正常连接上相应的UDP端口，但是quic连接不上，客户端连接timeout，服务端没有日志输出

timeout: no recent network activity 我一开始也是 quic 用不了

https://github.com/fatedier/frp/issues/3378#issuecomment-1569416972 检查防火墙是不是开了 7000 的 UDP

开了 UDP 协议就好了。
