Local Minio server returns SignatureDoesNotMatch with iOS AWS S3 SDK v2.4.16

[laurentgdh]

Use case: upload & download data to / from Minio from an iOS app. I'm currently developing the project so I'm using Minio locally (using docker).

I'm using the AWS SDK v2.4.16 so I can change the endpoint and I made it my localhost (http://my-imac.local:9000) and I updated my access and secret keys but I get a SignatureDoesNotMatch error: "The request signature we calculated does not match the signature you provided. Check your key and signing method.".

Pointing to my local server:

AWSEndpoint *minioEndpoint = [[AWSEndpoint alloc] initWithURLString:@"http://my-imac.local:9000"];
AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:region 
        endpoint:minioEndpoint 
        credentialsProvider:credentialProvider];
[AWSS3 registerS3WithConfiguration:configuration forKey:s3RegionString];

Log on my localhost:

@laurentgdh AWS IOS SDK doesn't support endpoints with port in it for example "Host\":[\"my-imac.local\" - for example here aws-amplify/aws-sdk-ios#349

There is a way out btw please follow the issue here #4039 you can make it work if you configured Minio on port 80 or 443.

Closing this issue as duplicate.
