Error in curl::curl_fetch_memory(url, handle = handle) : SSL certificate problem: certificate has expired

[namsor]

curl --version

It could be that you need to update CURL to the latest version.

we recently have problems when querying v2.namsor.com using curl 7.61.1 with openSSL/1.0.2k (amazon linux 2 default)
we are not experiencing problems with updated chrome or curl 7.68.0 with openSSL 1.1.1d.

As a workaround, one can also run the following to skip the SSL verification:
httr::set_config(httr::config(ssl_verifypeer = 0L))
