Python请求在尝试发布到gfycat.com时给出错误('Connection aborted.','error('104'ECONNRESET'),))

我正在执行代码:

import requests

clientID = redacted
secret =redacted

filename = "temp2.gif"
datakey = '{ "title":"random title"}'

r = requests.post("https://api.gfycat.com/v1/gfycats", data = datakey)
gfyname = r.json()["gfyname"]
print(r.json())
print(gfyname)

params_ = {'client_id': clientID, 'client_secret': secret, 'grant_type': 'client_credentials'}

r = requests.post('https://api.gfycat.com/v1/oauth/token', data=str(params_))

access_token = r.json()['access_token']

headers = {'Authorization': 'Bearer {}'.format(access_token)}
print(headers)
data = {'key': gfyname}
url = "https://filedrop.gfycat.com"
files = {gfyname: open(filename, 'rb')}

r = requests.post(url, data=data, files=files, headers=headers)
print(r)

直到最后一个request.post()调用(当我收到错误消息时):

requests.exceptions.ConnectionError: ('Connection aborted.', error("(104, 'ECONNRESET')",))

我已经用gfycat api文档验证了请求端点/参数。我已经检查了 headers 以及 access_token . 我已经阅读了请求文档,我确实找到了一些修复的地方。现在我被困在这里,想弄清楚为什么连接会中断。
