Something is off with how OpenAI is managing capacity for ChatGPT Plus subscribers. Users are hitting "too many concurrent requests" error messages even after not touching the platform for multiple days - a problem that cuts directly against the main reason people pay $20 a month for Plus.
The error is designed for situations where a user has too many active sessions running simultaneously. But affected users report having only one session open and no recent usage, which rules out the obvious explanation. OpenAI has not publicly acknowledged the issue.
For anyone using ChatGPT as a daily work tool, this is a real reliability problem. The core promise of Plus over the free tier is priority access - you pay specifically to avoid rate limits and queues. When Plus subscribers hit the same walls as free users, the subscription is harder to defend, particularly when Claude and Gemini both offer competitive paid plans at similar price points.
The workarounds circulating among affected users - logging out and back in, clearing browser data, waiting it out - are stopgaps that require interrupting a workflow. None are acceptable if ChatGPT is part of a production process during a workday. Until OpenAI acknowledges and fixes the root cause, the most practical advice is to have a backup tool ready.
