V2ray Slow Dns Server [best] Jun 2026

If your V2Ray server's time is off by more than 30 seconds, TLS handshakes fail silently. The TLS retry mechanism forces a DNS re-query. You end up querying DNS 4-5 times to establish one connection.

Another critical factor is DNS poisoning and interference. In restricted network environments, ISPs often hijack or throttle standard DNS queries. If V2Ray is not configured to use encrypted protocols like DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT), the local network may interfere with the resolution process, leading to timeouts or redirected traffic. This struggle between the local censorship and the proxy's attempt to find a clean path often results in "hanging" connections, where a page takes several seconds to begin loading. v2ray slow dns server
