pixie python API client always failed to validate the apikey

[everestplusteam]

Describe the bug
I tried to connect self-hosted cloud with python API, and followed the instruction to generate apikey and cluster ID.
but the python sample code always failed with below errors:
Traceback (most recent call last):

I tried the apikey with/without the prefix of "px-api-", but all failed. I also unset the system proxy settings, but still no effect.

[everestplusteam]

I added server_url to my self-hosted cloud, but failed with no certificaiton.
px_client = pxapi.Client(token="px-api-03397708-2978-4710-9beb-e40e38096e57", server_url="dev.withpixie.dev", use_encryption=False)

Hi @everestplusteam, can you verify that your API key exists with the px cli. You can do so by running the following command:

$ PX_CLOUD_ADDR=dev.withpixie.dev:443 px api-key lookup
> Enter API Key (won't echo):  <Enter your key in the prompt>

Please provide the output for that command once you've had a chance to run it.

it is my output, but I still cannot connect to with my API key.

I resolved the issue, as local cluster used, I need to set the cluster_address instead using the default value.
