Zero Trust (Warp) disconnection when uploading files to a R2 bucket

What is the issue you’re encountering

Zero Trust (Warp) disconnection when uploading files to a R2 bucket. I can consistently reproduce the issue by uploading files to the R2 bucket via Forklift app on Mac. I haven’t tried any other R2 / S3 clients. I use DNS filtering with Cloudflare Gateway but I cannot see any blocked domains that might be causing this behavior. How can I troubleshoot the cause of this Zero Trust (Warp) disconnection?

I am seeing the same breakage when I use rclone too, so this is not an issue specific to Forklift application on Mac.

What do the WARP logs say? Have you tried using warp-diag?

First thing what I thought about :thinking:
