Error trying to run AddUser

[Alysty]

I've been trying to use the addUser method but I keep getting the error 'The request signature we calculated does not match the signature you provided. Check your key and signing method'

I assumed at first that my access key and secret key were wrong but then I used the same keys with the github.com/minio/minio-go/ library to call the BucketExists method and it worked.

I am initializing both of the libraries in very similar ways as shown bellow

func initializeMinio(minioendpoint string, accessKeyID string, secretAccessKey string)  (*minio.Client) {
	minioClient, err := minio.New(
		minioendpoint,·
		&minio.Options{
			Creds:  credentials.NewStaticV4(accessKeyID, secretAccessKey, ""),
			Secure: true,
		})
	if err != nil {
		log.Fatal().Msg(err.Error())
	}
	return minioClient
}

func initializeMinioAdm(minioendpoint string, accessKeyID string, secretAccessKey string)  (*madmin.AdminClient){
	mdmClnt, err := madmin.NewWithOptions(
		minioendpoint,·
		&madmin.Options{
			Creds:  credentials.NewStaticV4(accessKeyID, secretAccessKey, ""),
			Secure: true,
		},
		)
	if err != nil {
		log.Fatal().Msg(err.Error())
	}
	return mdmClnt
}

I am also calling the addUser function in what I assume is the correct way

//access_key is a random string of letters and number of size 20 and secret_key is a random string of letters and numbers of size 40.
err = m.Minio.AdmMinio.AddUser(ctx, *access_key,*secret_key)
if err != nil {
	log.Error().Msg("Error making minio user: " + err.Error())
	return fiber.NewError(fiber.ErrInternalServerError.Code, "Error making bucket")
}

I have tried writting the access_key and secret_key as hardcoded strings to see if it was a problem with my random string generation but after trying with the values 'testaccesskey1234' and 'testsecretkey1234' I still received the same error.

does anyone know how to resolve this issue?

Are you using v4 or v3 ?

[Alysty]

I was using v4 but then I got a warning while using the api that said I should downgrade to v3, so now im using
github.com/minio/madmin-go/v3 v3.0.110
I did this before getting having the issue with the AddUser method. So changing it doesn't seem to be a viable solution, I can't update the minio server to use v4 instead.

[Alysty]

why was it closed, did I say something wrong ?

[Alysty]

@klauspost are posts related to v3 not allowed ?

[klauspost]

Oh, I thought you meant it was fixed by using v3.,

[Alysty]

oh no sorry, Ill edit the post to clear the misunderstanding

If you are using a load balancer or reverse proxy make sure it isn't changing the host.

[Alysty]

the server I am connecting to has a reverse proxy in front of it with the following configuration

        proxy_pass http://mys3server;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

it seems It is not changing the Host but I am changing it from https to http, is that a problem as well ?

[Alysty]

Just to add another bit of info, I tried using the command line tool to create a user from the same machine I run my code and it worked, so now I am unfortunately even more confused as to what the problem could be.
