Current behavior
I am using 1.2.3 self hosted version. I am using external S3, I used Cloudflare R2 and BackBlaze B2, When I am trying to create a project, I see the endpoint to upload image to S3 storage is failing.
ENV:
AWS_REGION: auto
AWS_ACCESS_KEY_ID: <access_key>
AWS_SECRET_ACCESS_KEY: <secret_key>
AWS_S3_ENDPOINT_URL: https://<account_id>.eu.r2.cloudflarestorage.com
AWS_S3_BUCKET_NAME: <bucket_name>
FILE_SIZE_LIMIT: 5242880
I do not know why this 501 not implemented error is coming and how do I fix it.
