rtcEngineConnectionDidLost

调用 agoraRtcEngine joinChannelByToken:token channelId:channelId info: nil uid:[[JBUserInfoManager shareManager].userInfo.uid unsignedIntegerValue] joinSuccess:^(NSString * _Nonnull channel, NSUInteger uid, NSInteger elapsed) 10秒直接回调rtcEngineConnectionDidLost 是什么问题

Hi,
可以切换移动网络试一下。是不是开启了防火墙?
开启token鉴权了吗?
