@delinend: I wonder if this is an OpenELEC specific issue (different version of curl), rather than RPi specific. Are you able to confirm this problem with OpenELEC on x86?

Edit: Kodi on Windows is using curl 7.39.1, OpenELEC is currently using 7.40.0, and has been since 11 Jan. Prior to this, from 6 Nov, OpenELEC used curl 7.39.0, so if you're seeing the problem with a December build, testing a version prior to 6 Nov might be useful as this would be using curl 7.38.0 (introduced 13 Sep).

My build #1106 from the evening of 6 Nov predates the 7.39.0 bump and might be worth a shot: download link, release notes.

You could then try build #1108 which bumped to 7.39.0 (not sure why it isn't in #1107, to be honest, so skip that build due to the uncertainty): download link, release notes.

Edit: The version of curl in use up tp 6 Nov would have been 7.37.1 - the commit on 13 Sep relating to 7.38.0 is actually reverting 7.38.0 back to 7.37.1, which I misread.
