The MCP I configured is context7, and I also used VPN, but my VPN can be guaranteed to be normal.

Yep, same problem. But no effective solution was found. Some
people suggested restarting codex , but this moethod is too troublesome.
Wait for this issue to be fixed.

Version 0.39 sames to have solved this problem. At least I haven't encountered this problem today. Try updating to the latest version.

I had this issue today. Was looking at my DNS logs while seeing the reconnect messages and noticed my host making calls to openrouter.ai

I had OPENAI_API_KEY env var set as part of Qwen CLI testing and this was causing the failure (and routing to openrouter for some reason?). I am using OAUTH auth to use Codex, not the API key.

Unsetting the env var re-enabled Codex CLI for me.
