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

@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?

@etraut-openai

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.

Token exchange failed: error sending request for url (https://auth.openai.com/oauth/token)

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!

Same to me.

I ran into the same issue on my Mac. After testing, I found that only Codex 5.3 in the CLI works; all models in the app, as well as the other models in the CLI, are unavailable for local tasks.

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.

This is not a network issue. Changing model works. I'm pretty sure there is a hidden rate-limit for openclaw bots that open ai doesn't tell. Because of this, I can't use Codex at all.

It seems like I encountered the same situation, but changing model only works for a short while for me.

Same issue. Looks like throtteling:

Edited settings.py +9 -0
Reconnecting... 1/5
Reconnecting... 2/5
Edited settings.py +0 -47
Reconnecting... 1/5
Reconnecting... 2/5
Reconnecting... 3/5

Same issue. threadID 019d5f83-d0c4-7ad0-a6cf-5b3b13cc287b

Super frustrating.

我每天也遇到这个问题

same question

i am having this issue with the CLI as well, it hard to tell exactly what is going on since i can't get any verbose output from the CLI, but it looks like its not even getting to the point of making any request to the server, since i am not seeing anything coming into my llama.cpp server from the codex cli session. and this is with a local model that i can use with the Zoo Code extension in vscode.

我一直提示这样，使用的codex客户端昨天下午还好好的，但是突然到了晚上就不行了，一直reconnecting...然后得到上面那一串。。。到底改怎么解决

I seemed to be able to mostly "fix" / work around this issue by following this link (https://learn.chatgpt.com/docs/config-file/config-advanced#azure-provider-and-per-provider-tuning) and setting:

[model_providers.azure]
name = "Azure OpenAI"
base_url = "****"
env_key = "****"
wire_api = "responses"
request_max_retries = 100 # should prevent disconnect issues
stream_max_retries = 100 # should prevent disconnect issues
stream_idle_timeout_ms = 300000 # should prevent disconnect issues

I don't know however if this works outside the Azure AI Foundry provider.
