Description
Shadowsocks version: 1.17.2 - 1.18.0 - 1.18.1 - 1.18.3
Client device: IPhone (iOS)
Server: Ubuntu 23 (Vultr and OVH)
Config:
{
"server":"207.148.90.219",
"mode":"tcp_and_udp",
"server_port": 55837,
"local_port": 1080,
"password":"d0c222d5bd70ab16f4df9dd3caa70a54",
"timeout": 60,
"method":"chacha20-ietf-poly1305",
"fast_open":true,
"nameserver": "8.8.8.8"
}
When I clicked on a link on Facebook, It returned an error screen. When I copied the link to the browser, It said dns_probe_finished_nxdomain. This issue only occurs on 4G network (OctopusNet Ltd), but not on Wifi (another ISP: Zelenaya Vladivostok Network).
It has no errors on the log. I tried to ping or traceroute to l.facebook.com or lm.facebook.com on my VPS, It still responded

Research direction
No source file, test, or entry point is identified. Start by reproducing the DNS failure with the reported iOS client, Ubuntu 23 server, 4G connection, Wi-Fi comparison, and nameserver configuration, then inspect the relevant DNS and proxy logs. Done would require isolating whether Shadowsocks causes the failure and defining a verified fix or reproduction boundary.
