Error “503 : Service unavailable” while trying to upload a video with the YouTube API

问题

Answered : The X-Upload-Content-Length value had a space in it.

Question :

I want to use the Youtube API to upload videos from a desktop application, in C++. I implemented the Resumable Upload, everything worked on Friday 19/07 in the afternoon, I could upload a couple of small videos, and since then I always get an error when using my app : "503 : Service Unavailable".

I found several threads treating this topic, it seems there were two solutions :

Retry the request several times in a row
Wait, it somehow works again after a while

Doing the same request again and again didn't solve it for me (I tried to do the request 5 times in a row, maybe I should do more requests ? How many ?). Here is a sample request and the response I get :

Request :

{
"snippet": {
"title": "My video title",
"description": "This is a description of my video",
"tags": ["cool", "video", "more keywords"],
"categoryId": 22
}
}

Response :

HTTP/1.1 503 Service Unavailable

Thanks for any help, I really don't know what to do right now.
