S3 Access column shows "Error" for all buckets

Question

In my console, all buckets show "Error" at the access column. Every operation results in an error, being it uploading, downloading, deleting or modifying files. The only thing I can do is creating a bucket. Afterwards however, I can't do anything with it.

I always had access rights and was previously working with my current account. I even tried it with the root account without any success. This seems to have happened miraculously over night as I wasn't working with S3 much during the past days.

N.B. I don't use any other APIs beside the console.

In your IAM policy permission, you have to add following permission for S3 console to list all your buckets properly (without error).

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Console_List_S3_Buckets",
            "Effect": "Allow",
            "Action": [
                "s3:GetBucketLocation",
                "s3:ListAllMyBuckets",
                "s3:GetAccountPublicAccessBlock",
                "s3:GetBucketAcl",
                "s3:GetBucketPolicyStatus",
                "s3:GetBucketPublicAccessBlock"
            ],
            "Resource": "*"
        }
}
