DNS typically runs on UDP. If the network is unstable, packets are dropped, leading to slow retries.
Before changing anything, collect data.

Understanding and Fixing V2Ray Slow DNS Server Issues V2Ray is a powerful network proxy tool designed to bypass internet censorship and secure user privacy. However, users frequently encounter performance degradation due to improper DNS configuration. A "v2ray slow dns server" bottleneck occurs when the time taken to resolve domain names exceeds the actual data routing time. This guide breaks down why this happens, how to diagnose it, and the exact configurations needed to fix it. Why DNS Latency Ruins V2Ray Performance DNS typically runs on UDP
Make sure you have a rule that directs your secure DNS traffic directly to the proxy or freedom outbound, depending on your needs. For instance, if you want your encrypted DoH traffic to bypass local censorship, ensure the outbound tag handles it correctly:
If your provider supports it, enabling DoH can sometimes be more stable than raw DNS queries. "dns": "hosts": "domain:v2ray

Hardcoding the IP address of your V2Ray server domain prevents a "chicken-and-egg" loop where V2Ray needs to resolve its own server IP using a DNS system that isn't running yet. Step 3: Fix Server-Side DNS Latency
