[BUG] transient network issue only on Crusoe GPUs

[lucataco]

Summary of the bug

Crusoe GPUs are blocking network requests to Replicate, specifically our base images
Thus, the team is unable to use those GPUs for any kind of dev work.
Seeing a "Bad Gateway" error that only shows up on Crusoe gpus.

Steps to reproduce

1. Startup any CRUSOE gpu on Brev (ex A100)
2. Open shell in cloud GPU
3. Install cog (github.com/replicate/cog)
5. Make a default Cog model with `cog init`
5. Run `cog build` to see the gateway error at the end

Expected vs actual behavior

Expected: Image built as cog-test
Actual: Failed to build Docker image: failed to solve: failed to resolve source metadata for r8.im/cog-base:python3.13: failed to do request: Head "https://r8.im/v2/cog-base/manifests/python3.13": Bad Gateway
