I've been getting this issues for several days now. Reported multiple times via Feedback in Codex app, the latest being 019d1fff-5705-7092-9468-30adf07dfbdc
Same. Running 5.4 (fast) xhigh in codex app macos. Context window was 88% full. I did have VPN on and it failed with this error 3 times. I just switched VPN off and now it's working, similar result to what another user reported above.

Thank you @gwest1000 I've just turned off my vpn and it has worked again. I've had the VPN on all day and compacting has occurred multiple times, but the issue has happened a couple of times today. Strange but working now, cheers
try this skill, https://github.com/haibindev/golast, It recovers the last actionable request from a crashed or compacted session, so you can pick up exactly where you left off.

Turning off VPN has been consistently working for me but this is obviously not a fix, as I and many others prefer to have VPN on generally. I'm getting this error daily, and it's a pain.

It seems this issue occurs by using VPN... I turned off and works fine. But shouldn't be doing that.
