Our relevant example is alright. Could you provide a simplest demo for us to reproduce the problem.

buruoyanyang commented 1 year ago

Our relevant example is alright. Could you provide a simplest demo for us to reproduce the problem.

Here is demo https://github.com/buruoyanyang/TestNacosWithGatewat And in version 2021.1 is ok(with spring-cloud version is 2021.0.5, and the spring-boot version is 2.6.13)

123liuziming commented 1 year ago

You may need to use the nacos 2.x server, using a lower version of the nacos server will cause you this problem @buruoyanyang

123liuziming commented 1 year ago

The versions of the Nacos client and server need to match. I use your example to connect to a nacos-server which version is 2.0.3.1. It is all right.

buruoyanyang commented 1 year ago

my nacos version is 2.1.2, it is not ok

buruoyanyang commented 1 year ago
