根因分析
名称解析器(DNS 或自定义)返回了空地址列表,通常由于没有就绪端点的无头服务,或格式错误的 target URI。
English
The name resolver (DNS or custom) returned an empty address list, often due to a headless service with no ready endpoints, or a malformed target URI.

无效尝试
常见但无效的做法:
-
60% 失败
Bypasses resolution but then dials the literal string as an address, which may not be a valid host:port.
-
90% 失败
No addresses means every dial fails; retries never produce an address.
