Looks like you are using http for the upload call. I have seen this error returned from sites for this reason before.

The HTTP error 503 means "Service Unavailable". It is usually returned by a server when it is unable to handle the request due to a temporary overloading or maintenance of the server.

After checking the API documentation for wechat, I notided this:

4. This API must be used via HTTPS.

And then I noticed this in the Q&A:

Q: Which server should I send API requests to?

A: If you have an International Official Account, use api.wechat.com.

If you have a China Official Account, use api.weixin.qq.com.

So, in your case I think you need to use https, and the domain api.wechat.com, like this:

response = requests.post('https://api.wechat.com/cgi-bin/media/upload', params=params, files=files)
