TimeoutError while generating AWS s3 Presigned URL - amazon-web-services

Question

I've created a route that generates a pre-signed URL to upload an object to AWS S3. It was working initially but lately, it's returning a Timeout Error.
Here is my controller code:
async (req, res, next)=>{
const BUCKET = req.params.bucket;
const KEY = 'myKey_'+ uuid.v4();
const EXPIRATION = 60 * 60 * 1000;
let signedUrl;
try{
// Also have a configuration file ~.aws/.credentials
const s3 = new S3({
accessKeyId: process.env.AWS_ACCESS_KEY,
secretAccessKey: process.env.AWS_SECRET_KEY,
region: 'ap-south-1'
});
// creating a s3 presigner obj
const signer = new S3RequestPresigner({ ...s3.config });
// creating file upload request
const AWSUploadRequest = await createRequest(s3, new PutObjectCommand({
Bucket: BUCKET,
Key: KEY
}));
const expire = new Date(Date.now() + EXPIRATION);
// creating & formating presigned URL
signedUrl = formatUrl(await signer.presign(AWSUploadRequest, expire));
console.log(`Generated Signed URL: ${signedUrl}`);
}catch(err){
console.log(`Error creating presigned url ${err}`);
return next(
new ErrorResponse(
`Error while generating aws s3 presigned url`,
500
)
)}
res.status(200).json({
signedUrl
})
}
Here are my logs:
AWSUploadReq: {"method":"PUT","hostname":"s3.ap-south-1.amazonaws.com","query":{"x-id":"PutObject"},"headers":{"Content-Type":"application/octet-stream","user-agent":"aws-sdk-nodejs-v3-#aws-sdk/client-s3/1.0.0-rc.7 win32/v10.15.3"},"protocol":"https:","path":"/dammnn/myKey_file-c6f198d6-9e91-4892-8c88-8a49e15406c1"}
Error creating presigned url Error: TimeoutError
It's very vague as to why the request is getting timed out. Looking for some guidance on the same. Thanks.
