I had this same issue last time I downloaded the connector, but I can't remember how I fixed it, so here we are again.

I have accepted the terms and conditions, everything is up to date, I just get an x every time I try to download from site accessed via proxy even though everything else loads. The proxies follow this format https://www-jstor-org.libproxy.berkeley.edu/stable/3178619.

I have https://%h.libproxy.berkeley.edu/%p and %h.libproxy.berkeley.edu/%p set as proxies.

Please help before I hurl my computer out a window! Debugging number D893756034.
