@bradlipovsky a few months ago we updated the client and broke backward compatibility. I am so sorry for this - it was a necessary evil as we were connecting to sliderule over non-standard ports and some firewalls were having issues with it. It looks like you are using one of the older clients. Can you update to the latest Python client and give it another try?

Here is a link to some instructions on updating the client: http://icesat2sliderule.org/rtd/getting_started/Install.html
