IT is similar to #19979 but with a more recent codex version and different Auth method.

Also seeing this on Codex Desktop for macOS.

Error:

Error running remote compact task: stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses/compact)

This is still happening today (2026-05-07).

This happens to me on 100% of compact tasks, in VSCode extension and Codex CLI (Linux). Using subscription, not API key.

Thanks for reporting this problem. Until recently, Codex used a separate endpoint and server-side logic for compaction. We recently switched to a more robust approach where the compaction logic is moved locally using the same endpoint as normal turns. This eliminates "remote compaction" errors and increases the stability and reliability of compaction operations. If you see further problems with compaction, please use /feedback and open a new bug report.
