Error when trying to download from VIMEO:
"An SSL error occurred: The issuer certificate of a locally looked up certificate could not be found"
Having the same problem. Using macOS Sierra.
Got the same problem. After having downloaded from vimeo for months without any problems I now get the message "On this site no video can be found". I have not changed any adjustments and have been downloading quite a few videos from the same (vimeo-)contributor.
Any ideas what is going wrong?
