Can anybody help me understand why I am suddenly getting the following error message? ERROR: Dropbox API: (6) Couldn't resolve host 'content.dropboxapi.com'
That looks like a DNS failure. The content.dropboxapi.com domain is resolving properly for me right now though, so it sounds like your computer/server may be having network or DNS issues. You or your hosting service would need to look into that on your side. Apologies I can't be of more help!
It should be enough to say that you're unable to resolve 'content.dropboxapi.com'. Make sure to include any and all error output you're getting though.
