dubbo运行报错，启动正常

服务可以正常启动   但是一运行就报以下错误

org.apache.dubbo.rpc.RpcException: No provider available in [invoker :interface com.shanjupay.transaction.api.PayChannelService -> spring-cloud://localhost:9090/org.apache.dubbo.registry.RegistryService?application=merchant-application&check=false&dubbo=2.0.2&interface=com.shanjupay.transaction.api.PayChannelService&lazy=false&methods=queryPlatformChannel,bindPlatformChannelForApp&pid=13968&qos.enable=false&qos.port=22310&register.ip=192.168.172.1&release=2.7.3&retries=-1&side=consumer&sticky=false&timeout=3000&timestamp=1616575264220,directory: org.apache.dubbo.registry.integration.RegistryDirectory@26fadd98, invoker :interface com.shanjupay.transaction.api.PayChannelService -> nacos://127.0.0.1:8848/org.apache.dubbo.registry.RegistryService?application=merchant-application&check=false&dubbo=2.0.2&interface=com.shanjupay.transaction.api.PayChannelService&lazy=false&methods=queryPlatformChannel,bindPlatformChannelForApp&pid=13968&qos.enable=false&qos.port=22310&register.ip=192.168.172.1&release=2.7.3&retries=-1&side=consumer&sticky=false&timeout=3000&timestamp=1616575264220,directory: org.apache.dubbo.registry.integration.RegistryDirectory@23ad2d17]
 

找不到服务提供方。

启动那个有界面的后台了么，可以去看看后台服务起来了吗

怎么解决的，我也是同样的问题
