[pdal] Python pipeline not reading ept.json

[Gelder, Brian K [A&BE]]

Hello,
I'm a pdal newbie and I'm trying to figure out how to successfully read ept.json files. I have pdal 2.4.2 installed via Conda on Python 3.9 on Win 10 and am able to use the pipeline to process local datasets like interesting.las in the tutorials. However, when I try to read EPT web resources, like in https://pdal.io/en/latest/tutorial/iowa-entwine.html, I receive the following error:

Traceback (most recent call last):
  File "<pyshell#15>", line 1, in <module>
    pipeline2.validate()
  File "C:\Users\bkgelder\AppData\Local\ESRI\conda\envs\pdal-testing-env\lib\site-packages\pdal\pipeline.py", line 43, in validate
    return self.p.validate()
  File "libpdalpython.pyx", line 185, in pdal.libpdalpython.PyPipeline.validate
RuntimeError: readers.ept: Could not read from s3-us-west-2.amazonaws.com/usgs-lidar-public/IA_FullState/ept.json

I get similar failure when I tried to query the smaller Hurricane Florence dataset Vishu wrote about last week. I can view the ept.json files in Firefox. Is there a firewall setting I'm missing?

Thank you,
Brian
