Cloudflare Tunnels无法建立隧道的解决办法

zhou Lv8

今天在使用CloudFlare的tunnel,给NAS搞一个公网访问,结果发现从NAS里面运行docker,Cloudflare客户端无法建立连接,错误如下:

2024-11-26T09:05:39Z ERR Failed to dial a quic connection error="failed to dial to edge with quic: timeout: no recent network activity" connIndex=0 event=0 ip=198.18.0.50

网上查询了一下,大家的说法是NAT,防火墙,再就是客户端的协议方式,最后查了一下自己的网络,排除了NAT,防火墙问题,于是就按照下面的方式修改协议,在docker命令中增加--protocol http2即可,此时强制指定协议为http2,使用的是TCP,这样就不会被运营商阻断了。当然,也可以设置为–protocol auto ,开启自动切换,默认依然是quic,但是失败后可自动切换到http2。

sudo docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run --protocol http2 --token <YOUR_TOKEN>

心想这样应该就可以了吧,结果又报了下面的错误:

2024-11-26T09:11:24Z ERR Unable to establish connection with Cloudflare edge error="TLS handshake with edge error: EOF" connIndex=0 event=0 ip=198.18.0.49

又是查网络发现这个issue说的靠谱,我家里是软路由透明代理,DNS应该是使用了旁路由的DNS,导致了这个问题,于是我把NAS的dns地址手动指定为我的主路由地址,再次运行docker,查看日志,it works!
