Codex CLI Issue: Connection closed prematurely while waiting for the model. Please try again

API Codex CLI
1

Since last night (5-23-25 8P CST) have had horrible results with Codex CLI. Been using Codex for months with no issues. Today I am having the same issue as last night:

    system
    ⚠️  Connection closed prematurely while waiting for the model. Please try again.

Using the same model as always: 04-mini.

What’s up with this? Balance $ is positive and have not even used up my free credits for sharing data with openai.

Today I show usage even though message is saying connection closed:

I have been using project keys for many months, no issues.

It dawned on me to try a regular api key like sk- and it is now working. Using sk-proj-2 does not work.
