Issue with Cloudron Backup via Cloudflare Tunnel to MinIO

[vadim]

I'm trying to set up Cloudron backups to a MinIO server running in my office. The Cloudron instance is on a VPS, and I'm connecting to MinIO through a Cloudflare Tunnel.

The problem: when backing up through the tunnel, I get this error:

Retrying (5) copy of snapshot/app_533f490e-6cb6-4da9-b014-647758d34c13.tar.gz. Error: XMLParserError: Non-whitespace before first tag. Line: 0 Column: 1 Char: e 524

However, if I expose MinIO directly via NAT and port forwarding on my router (without the tunnel), backups work just fine.

Other services work well with Cloudflare Tunnels — the issue seems specific to Cloudron + Cloudflare Tunnel + MinIO.

Thanks in advance!

Looks like Cloudflare is interfering here and changing the data in transit? You would have to contact Cloudflare about this, but I have no high hopes that this would get anywhere.
