Feign reports an error: com.netflix.client.clientexception: load balancer does not have available server for client: XXX

The first step is to check whether the name of the service called by feign is correct. Of course, this is a common way. Only when you find that the name is right can you search on the Internet. My problem is that the original call was good. As a result, the versions of springcloud and spring boot were changed to a lower level, but they couldn’t be adjusted. The service name was not changed. So I found that there was a horizontal bar on my service name. Once the horizontal bar was removed, it passed and I was drunk. So I specially wrote an example. It was really the reason for the horizontal bar

com.netflix.client.ClientException: Load balancer does not have available server for client: server-1

Summary: do not add any symbols to the service name. The lower version is incompatible, such as 2.2.6.release hoxton.sr3 I use, and the higher version is OK
