你是用什么方式发现节点的？ cluster.discovery 相关的配置是怎么配的？

现在发现了 ’ emqx@node2.emqx.io’ 节点但是连不上他。我注意到 ’ emqx@node2.emqx.io’ 这个节点名里有一个空格，这应该是个配置的问题。

是的已经处理了,警告也消失了,但是新问题是首次连接的时候会出现 授权错误, 然后设置自动重连后有时候可以重连上有时候需要很久才行

你的 emqx 版本是哪个？你可以尝试升级到最新版本试试看，怕是已修复过的问题。 4.4.19 (开源）或者 4.4.23 （企业版）。

通过你的描述，我觉着很可能是跟 redis 的 idle-timeout 配置有关。你检查一下，是不是 redis 有启用发呆断连这种配置，关掉它试试看。

用的这个个版本: emqx/emqx:4.4.10
