Imgur block my IP?

Question

I upload 12 image to imgur every half hour.

But meet this issue.

Imgur ERROR message: {'exception': [], 'code': 429, 'type': 'ImgurException', 'message': 'You are uploading too fast. Please wait -0 more minutes.'}

I don't understand why is -0 minutes. I guess I reach my rate limit, so try to see my rate limit. But it look normal.

{
    "data": {
        "UserLimit": 2000,
        "UserRemaining": 2000,
        "UserReset": 1521378886,
        "ClientLimit": 12500,
        "ClientRemaining": 12500
    },
    "success": true,
    "status": 200
}

I try in different machine in same CLIENTID, the upload function work fine.

Did my IP be banned by imgur? When will they free my IP?

UPDATE:

I find out each IP imgur will treat different user. But my machine curl credits api. The response look fine.

curl --request GET \                                                                                                        
--url 'https://api.imgur.com/3/credits' \
--header 'Authorization: Client-ID xxx'

{"data":{"UserLimit":500,"UserRemaining":497,"UserReset":1521394842,"ClientLimit":12500,"ClientRemaining":12457},"success":true,"status":200}⏎

When I run upload image. It still will show

Imgur ERROR message: {'message': 'You are uploading too fast. Please wait -0 more minutes.', 'type': 'ImgurException', 'code': 429, 'exception': []}

However, other image function work fine such as get image.

Apparently "there is an upload limit of 50 images per IP address per hour".

I don't know why they don't state this on the main api.imgur.com page, it's essential information for an API...
