Stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses)

When using codex from the CLI I am frequently getting a "Reconnecting" message and codex fails to reconnect after 5 attempts. I see this message Stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses). The thread ID is 019caee5-4280-7290-a4ca-6456a7f599c4

From your logs, this looks like a basic network connectivity issue. We see these frequently with VPNs and proxies, but it might also just be flakiness with your connection.

Cool Thank you. For additional context, I use Tailscale and have a hardwired connection to my router. No other VPNs running other than Tailscale. I see this issue about once an hour or so, but it's unpredictable.

@etraut-openai My thread ID is 019caf1f-0131-7303-8f3c-5d92be272875, any idea what is going on? Not using a VPN.

@hhmoud-acerta, yours looks like a connectivity issue as well. You mentioned you are not using a VPN. How about a corporate proxy or firewall?

Hi @etraut-openai , looks like even I'm facing the same issue, both on cli and codex app. I dont use any VPN nor behind any corporate firewall or proxy. It works well for few hours and then doesn't at all for few.

I started getting this at my office on Wednesday evening March 4, 2026 and regularly receiving them at my home since then Wednesday through Friday March 6, 2026.

Somebody recommended that I log out & that would fix it.

I took the bait... desperate to get this working again and then I can't get logged back in!
Five separate times (& counting) without luck!
