调用任何dubbo提供者服务都报错

Question

com.alibaba.dubbo.rpc.RpcException: Failed to invoke the method getMap in the service com.mama.cloud.date.api.service.ApiSerivce. Tried 3 times of the providers 101.5.61.2:30063 from the registry 101.5.230.85:2181 on the consumer 101.5.61.3 using the dubbo version 2.5.5-SNAPSHOT. Last error is: null

在本地调用都能成功，但部署到测试服务器就一直报错，困扰两天了，有人知道怎么解决吗，dubbo-admin上都是正常的
