Cannot connect to the minio server from another node. #144

Closed mivenHan closed 4 months ago

I start a minio server in a node with IP 10.2.64.81.

The output is that: `$ docker run --net=host quay.io/minio/minio server /data --console-address ":9001" Formatting 1st pool, 1 set(s), 1 drives per set.

Docs: https://min.io/docs/minio/linux/index.html Status: 1 Online, 0 Offline. STARTUP WARNINGS:

I modify the example code for examples/ListBuckets.cc.

` // Create S3 base URL. minio::s3::BaseUrl base_url("https://10.2.64.81:9000");

// Create credential provider. minio::creds::StaticProvider provider( "minioadmin", "minioadmin"); `

The output is always HTTP Error. unable to list buckets; server failed with HTTP status code 0

However, I could use the mc comand to make the buckets and upload the objects. `

mc admin info myminio

512 MiB Used, 1 Bucket, 1 Object 1 drive online, 0 drives offline, EC:0 `

So, what's wrong with the code? The mc comand could get the right result, but the c++ could not connect the minio server from another node.

I add one line code "client.Debug(true);"

The output is below.

I also test for the minio-py, it meets the same problem for SSL.

@mivenHan You are connecting HTTP as HTTPS or vise versa. Please check you endpoint.

mivenHan commented 4 months ago

I change the IP to minio::s3::BaseUrl base_url("http://10.2.64.81:9000/"); minio::s3::BaseUrl base_url("10.2.64.81:9000/");

Still the same error.

If you don't give a secure flag, the default is true. If you are not able to access the minio docker instance, consult your docker provider. Nothing can be done at client side
