Problem susoapi

Continuing the discussion from Export data api:

Hello @arthur-shaw , I had to use an old R´s version and untick the mark on using the secure download method HTTP. Additionally, I selected Global (CDN) as the primary CRAN repository.

This looks more like R/RStudio problem than Arthur’s susoapi package problem. Perhaps even some sort of communication problem if it is not possible to establish secure communication.

What does the last option do? “Use Internet Explorer library/proxy for HTTP”? Would anything related to below cause disruptions?
