5xx type of error is a server side error. 5xx类型的错误是服务器端错误。 List of HTTP status codes at wiki states that Error code 503 means The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state. 维基的HTTP状态代码列表表示错误代码503表示The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state. The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state. So, in short your server seems to be down. 所以，简而言之，你的服务器似乎已经失败了。

As you have stated that the Error is 503 from server, Please check this link once. 如您所说，服务器的错误是503，请检查此链接一次。 It states that the 503 error may occur due to following reasons: 它声明可能由于以下原因而发生503错误：
- Obtain an IP address from the IP name of the site (the site URL without the leading 'http://').
- Open an IP socket connection to that IP address.
- Write an HTTP data stream through that socket.
- Receive an HTTP data stream back from the Web server in response.

It's hard to tell without actually seeing your VCL file... but taking account that you get that error while uploading (a POST request) I guess you're hitting one of the the backend timeouts[1]. 没有实际看到你的VCL文件很难说...但是考虑到你在上传时遇到了这个错误（一个POST请求）我猜你正在击中其中一个后端超时[1]。
Try to rise timeouts and see if the error persists: 尝试提高超时并查看错误是否仍然存在：
backend default {
.host = "your.host.tld"; //Use your current setting
.port = "XXX"; //Use your current setting
.connect_timeout = 300s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
}
