全量同步异常

[loverkoo]

Is this a regression?

Yes

Description

pika4.0.1同版本之间(3.5.5版本有同样问题)，新建slave，出现无法全量同步。
网络环境，master在内网 ，只有内网ip，slave在外网，slave去master同步只能通过路由nat方式去连接。
只是全量同步有问题。
增量没问题，因为如果是新建两个空库，有机会同步成功，状态也能看到up。
但实际上不是空库，因为无法完成全量同步，也无法进入到增量同步状态。

日志是这样不断重试，直到最后完全失败后终止同步了

是否是3.5版本的Pika和4.0的Pika做主从关系

Is there a master-slave relationship between Pika version 3.5 and Pika 4.0?

不是，全是同版本同步。
4.0.1版和3.5.5版都有问题，现象一样。

Is there a master-slave relationship between Pika version 3.5 and Pika 4.0?

No, they are all synchronized with the same version.
Both versions 4.0.1 and 3.5.5 have problems, and the phenomenon is the same.
