# A/B 对比：QUIC(UDP) vs HTTP/2(TCP)
|
||
#
|
||
# 背景：
|
||
# 隧道日志里全是 QUIC 超时：
|
||
# Failed to dial a quic connection ... no recent network activity
|
||
# Connection terminated error="control stream error"
|
||
# 全是 "Failed to accept QUIC stream"
|
||
# 而 cloudflared 自己回退成 protocol=http2 之后**注册成功了**。
|
||
# 所以怀疑这条 4G 线路在丢 UDP 包，TCP 反而稳。
|
||
#
|
||
# 每边跑 90 秒，每 2 秒探一次公网，对比不通率。
