Strange problem uploading to youtuibe

[jamedia.uk]

Hi I am using FCPX 10.1.4 (I am still on OSX Mavericks) and all of a sudden when I share to youtube all goes well until the finalising of the upload i.e. 99% has uploaded and It fails. This has only just started to happen and is a hard fault. No problem uploading to Vimeo. Also no problem drag and drop to youtube. Though the end of the upload the time remaining jumps about a bit (last 15 seconds or so) and the "dome" button goes live and works before the upload is 100%

Does anyone have any ideas what might be happening?


SOLVED THE PROBLEM> IT seems that in JULY 2016 You Tube changed the authentication system. It was fixed in FCPX 10.2.2 and later. So for pre 10.2.2. users IE those still on Mavericks you have to share computer and manually upload.

SO no one is having any problems with YouTube and FCPX V10.1.4?

It is a hard error on both my youtube accounts. Both log in OK and seem to upload 99% the it fails.
This is strange.
