无法从本地连接AKS上的Daskhub，请求排查404问题

部署背景 #

基于DaskHub Helm Chart在AKS测试集群部署，修改了以下配置：

• 设置API Token
• 将traefik替换为LoadBalancer
• 配置gateway.prefix: "/services/dask-gateway"

AKS集群服务状态 #

api-test-dask-gateway             ClusterIP      10.0.xxx.yyy    <none>           8000/TCP       2d2h

当前状态 #

Jupyter Notebook可正常登录使用，但本地PC连接Dask Gateway时持续出现404错误。

尝试的代码及错误 #

第一次尝试代码 #

import os
from dask_gateway import Gateway
os.environ['JUPYTERHUB_API_TOKEN'] = "abcde"
gateway = Gateway(
    address="http://ii.jjj.kkk.lll/services/dask-gateway",
    auth="jupyterhub"
)
gateway.list_clusters()

返回错误：

<div class="error">
  <h1>
    404 : Not Found
  </h1>
<p>Jupyter has lots of moons, but this is not one...</p>
</div>

第二次尝试代码 #

import os
from dask_gateway import Gateway
os.environ['JUPYTERHUB_API_TOKEN'] = "abcde"
gateway = Gateway(
    address="http://ii.jjj.kkk.lll/services/dask-gateway",
    proxy_address="gateway://aa.bbb.ccc.ddd:80",
    auth="jupyterhub"
)
gateway.list_clusters()

仍返回相同的404错误。
