After enabling Anti-DDoS Pro protection for the domain name, I cannot upload large files to the website, and the system throws a 413 error.
Anti-DDoS Pro limits the maximum file size allowed to be uploaded to the website. If you attempt to upload a file that exceeds 300 Mb in size, a 413 error is thrown.
Compress the file before uploading it, and make sure that the file you upload is smaller than 300 MB.
We recommend that you store large files in an Alibaba Cloud OSS bucket, rather than uploading it directly to the origin ECS server.
For occasional upload needs, you can temporarily map the HOST name to the IP address to bypass Anti-DDoS Pro, and directly access the ECS instance to upload the file.
