I don't know what happened in the last 24 hours that caused this thing to break, but it had been working perfectly for 3 years, non stop without issues. Trust me, I haven't changed any code. As a matter of fact, I haven't pushed code for 2 weeks.
Basically, I am using Laravel 6 and Laravel Vapor to upload files to S3 using the Signed URLs mechanism that the framework provides. Ever since this morning, I am seeing the following issue. The AWS PHP SDK is 3.148.3, by the way.

CodePudding user response：
Three things to check:
- Region mismatch, the bucket is in region X but CLI/SDK goes to Region Y.
- A corruption or unusual setting in your AWS CLI profile, reset the profile, check if access key and secret are still valid.
- CORS configuration not containing
<AllowedHeader>*</AllowedHeader>
Otherwise could you share some more details on the code that causes the error?
CodePudding user response：
I found the solution. I had to remove the following in the headers: x-amz-acl. I do not know why this was the problem but it seems to have worked. Hope if anyone comes across this in the future, try this solution.
if ("Host" in headers) {
delete headers.Host;
delete headers["x-amz-acl"];
}
