[gao746700783]

in my situation, flutter and android sdk is used,but can't find a way to ignore x509 errors:

I/GoLog ( 709): 2025-11-28 01:20:32.078 WARN [PID:709] [v3.8.3-patch.3] [flutter/APad] [interaction/long_conn_mgr.go:207] reConn {"error": "tls: failed to verify certificate: x509: certificate signed by unknown authority"}

// in android
连接服务器失败(10000tls: failed to verify certificate: x509: certificate signed by unknown authority)
