Can not download from thetvdb anymore

Strange behavior, I can not download from the thetvdb in subler anymore. I am not sure what have change, I updated to latest version of OS X, and now I can not get the data anymore. I can not even access the site in a browser.

I tried on a windows pc, I could open the site in inertness explore (desperate I know), so have apple somehow blocked thetvdb, or what is going on?
