At present, the APISIX nacos plug-in does not perform dns resolution on the back-end host it gets ([code location](https://github.com/apache/apisix/blob/master/apisix/discovery/nacos.lua#L303-L330)), so if the domain name is configured in nacos, it will be directly used as the parameter of `balancer.set_current_peer`, which will lead to `no host allowed While connecting to upstream` error. The configuration node on the Dashboard page will first do dns query and then give `balancer.set_current_peer`, so it can work. [code location](https://github.com/apache/apisix/blob/master/apisix/init.lua#L166-L166) So the error you encountered is in line with expectations, we can further consider whether service discovery should support configuration in the form of domain names. -- This is an automated message from the Apache Git Service.
