通过WebSocket与代理访问Azure EventHub遇AMQP连接认证错误求助

我所在网络要求使用代理，且仅允许通过HTTPS（443端口）连接。按照官方文档配置了代理参数与TransportType.AmqpOverWebsocket，编写的EventHub生产者代码如下：

async def run():
    producer = EventHubProducerClient.from_connection_string(
        "Endpoint=sb://my_eh.servicebus.windows.net/;SharedAccessKeyName=eh-sender;SharedAccessKey=MFGf5MX6Mdummykey=",
        eventhub_name="my_eh",
        auth_timeout=180,
        http_proxy=HTTP_PROXY,
        transport_type=TransportType.AmqpOverWebsocket,
    )

运行时出现如下错误：

File "/usr/local/lib64/python3.9/site-packages/uamqp/authentication/cbs_auth_async.py", line 74, in create_authenticator_async
    raise errors.AMQPConnectionError(
uamqp.errors.AMQPConnectionError: Unable to open authentication session on connection b'EHProducer-a1cc5f12-96a1-4c29-ae54-70aafacd3097'.
Please confirm target hostname exists: b'my_eh.servicebus.windows.net'

不清楚问题原因，该问题是否和GitHub上提到的相关Issue有关？
