Error in curl::curl_fetch_memory(url, handle = handle) : Couldn't resolve host 'api.dropboxapi.com'

[ero]

Since some time, rdrop 0.7 and now 0.8 - when I make a clean auth in session (removed all object from globalspace / cleaned cache files from project -> rm .httr-oauth) and make a succesfull auth in the session dropbox does work.

But when I save the session and then make a drop_auth(rdstoken = "data/droptoken.RDS") I get a curl error.

Error in curl::curl_fetch_memory(url, handle = handle) : Couldn't resolve host 'api.dropboxapi.com'

@ero Could you provide a more reproducible example? What do you mean when you say "save the session", are you saving your workspace to an Rda file?
