[joshiste]

sorry but I can't read chinese. What does the exception tell?

[hellotoworld]

The exception is : Java.io exception: the remote host forces an existing connection to be closed.

[joshiste]

Doesn't look like a SBA problem. I guess there is maybe some firewall between (or on the remote host) resetting the connection

[liubin0211]

@hellotoworld 这个问题你解决了吗？我今天遇到了，我的防火墙也是关闭的

[hellotoworld]

@liubin0211 我的是因为springbootadmin和springboot的版本不一致导致的

[joshiste]

@liubin0211 @hellotoworld please use english so that more people can participate

@liubin0211 @hellotoworld please use english so that more people can participate

They guess that's because the different version between SpringBoot and SBA.
