Have you figured out what is the problem? I'm seeing the same issue

In my case I was able to overcome the issue by configuring a DNS resolver and uploading the code via USB

import network

# set CloudFlare DNS resolver
network.ipconfig(dns="1.1.1.1")

@felmue There doesn't seem to be an answer in the thread you mentioned.

I'm seeing this issue when trying to read from a CO2 sensor.
