■ Error running remote compact task: stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses/compact)
Compaction almost never works, leaves session hung and ends current conversations. When I keep telling it to proceed in order to restart compaction, sometimes it just resets with no context at all.

What steps can reproduce the bug?

Have codex compact the context.

What is the expected behavior?

Expected behavior is context compaction and session continuation

Doesn't seem to go away until a new session is started.
