Which version of V2Ray are you using?

Which version of V2Ray are you using?

Thanks for your answer.

when I posted this issue, I use:

$ sudo systemctl status v2ray.service
...
V2Ray 5.6.0 (V2Fly, a community-driven edition of V2Ray.) Custom (go1.20.4 linux/amd64)
...

after updating to 5.9.0 hinted by your comment, the problem is still there.

Added info:
I use the server ipv6 address as the proxy when posting this issue (sorry for not saying that before) and use the google dns server "2001:4860:4860::8888"

$ sudo vim /etc/v2ray/config.json
    {
      "protocol": "vmess",
      "tag": "proxy",
      "settings": {
        "vnext": [
          {
            "address": "2401:...:3610",
...
    }   
  ],  
...
  "dns": {
...
    "servers": [
      "2001:4860:4860:0:0:0:0:8888",
      ...
    ]   
  },  
$ sudo vim /var/log/v2ray/error.log

$ dig +short @2001:4860:4860::8888 AAAA www.test-ipv6.com
# show nothing

It shows that www.test-ipv6.com doesn't have one ipv6 address.

Although the unavailability of ipv6 address for www.test-ipv6.com may not influence the strategy, I used one ipv4 server and the ipv4 dns server address, the above issue is still there. Hope the added infos can help someone who can help me with the problem to understand my issue more.

You are using V2Ray v4 configuration, but it has been changed in V2Ray v5 version. More details here: https://www.v2fly.org/v5/config/router.html
