  Status: the issue was closed as COMPLETED in its header, but the maintainer reopened it on 2026-08-28 because the bug still reproduces on comfyui-mcp 0.52.145, now including the segmented download path. A maintainer comment says a fix is being driven on branch fix/2356-seg-staging-progress; no fixed release is confirmed in this thread.

  The workaround used in the thread: when a multi-GB download appears stalled, issue action:"cancel", then re-issue the same action:"download". In the original report, an 8.74 GB qwen_2.5_vl_7b_fp8_scaled.safetensors download to text_encoders showed 83% in status, but cancel reported a 1.26 GB .partial in ~/.comfyui-mcp/cache/. Re-issuing resumed and reported 28%, which matched the on-disk size. On 0.52.145 the maintainer saw a 19.53 GB segmented download report "PROGRESS UNAVAILABLE" for 32 minutes while its .seg staging file grew; cancel left a 4.23 GB .partial, and re-issue resumed at 22%.

  The reporter's view is that status progress is not reconciled against the .partial size on disk, and that when progress is unavailable the row degrades to a bare "still streaming" with no explanation. The reporter suggested deriving progress from the .partial size and adding a stall indicator; these are suggestions, not confirmed changes. General advice: for large downloads, do not rely on status percentages alone. If the on-disk file stops growing, cancel and re-issue, which the thread shows resumes the transfer.

  What a GitHub user tried on GitHub (Didn't work)

  Reporter ran action:"download" for an 8.74 GB Hugging Face file and polled action:"status" for about 1.5 hours. Status reached 83% and then lost its byte counts. action:"cancel" later reported only a 1.26 GB .partial on disk.

  What @artokun tried on GitHub (Worked)

  Reporter issued action:"cancel" and then re-issued the same action:"download". The download resumed and reported 28%, consistent with the 1.26 GB on-disk .partial.
