Big Capital and S3

Has anyone successfully configured both to work for document uploading? I keep receiving 401 error in browser console and it never changes. I have been trying for a few days now. No matter what I adjust I can't seem to get a log to generate as to what the issue is. I even tried both chatgpt and gemini to see if I am missing something. I have tried minio in the same stack as big capital and separately. I have created a user and buckets and even tried public access to the bucket with admin account. I can reach console without issue. I can access big capital no problem. All is local on a dedicated Ubuntu server. I have tried various versions of endpoint as well.
