Oh ok I didn’t catch that. Flickr sent me a mail, this might be of use to someone (the reason behind all this):
As you may have read on the Flickr code blog, we’ve updated all of the API endpoints to fully support SSL. You no longer need to use a special subdomain to access the API securely, and we want to make sure that all API communication adopts SSL.
Many of you have moved over to using SSL already, which is great! If you haven’t, it shouldn’t be much more work than updating your apps to call the API at: https://api.flickr.com/
We’ll be updating the blog with information as we get close to the switchover date, but here’s the most important info:
New API keys will be issued for HTTPS access only: as of 6 May 2014
First blackout test window: 3 June 2014, 10:00-12:00 Pacific Daylight Time (PDT)
Second blackout test window: 17 June 2014, 18:00-20:00 (PDT)
Non-SSL API deprecated: 27 June 2014, 10:00 (PDT)
During the blackout tests and after the 27th of June, calls to the Flickr API that are not over SSL will fail with an HTTP error code 403. We will also return an error message with (Flickr) code 95 and msg “SSL is required”.
