What is the issue you’re encountering

Tunnel modified “accept-encoding” header value from “gzip” to “gzip, br”, that breaks my origin server’s signature calc by headers, causes SignatureMismatch error.

What are the steps to reproduce the issue?

  1. Depoly MinIO server on my device in local netwrok, create a bucket.
  2. Depoly cloudflared on same device, settings on tunnel dashboard.
  3. Use a S3 api to access my MinIO bucket from tunnel, like “ListBucket” api, got “SignatureMismatch” error.

Cloudflare Tunnel settings are typically configured through the cloudflared command or configuration files (config.yml). Could you check if there are any related configuration setting in regards to this ?
