"Why is ChatGPT Not Working? Complete Troubleshooting Guide 2026"

If you've ever typed a prompt into ChatGPT only to be met with an error message, a spinning wheel, or a blank screen, you're not alone. Millions of users experience ChatGPT outages, slowdowns, and errors every month. This guide walks you through every common issue, how to diagnose it, and — most importantly — how to fix it.

Common Reasons ChatGPT Stops Working#

ChatGPT can break for a variety of reasons. Here are the most frequent culprits:

1. OpenAI Server Outages#

OpenAI's infrastructure handles billions of requests. When demand spikes or internal issues occur, the service goes down. Major outages have happened multiple times in 2025 and 2026, sometimes lasting hours.

How to check: Visit status.openai.com to see real-time service status. You can also check Downdetector for user-reported issues.

2. Rate Limits and Capacity Restrictions#

Even when ChatGPT is technically online, you may hit rate limits — especially on the free tier. OpenAI throttles usage during peak hours, and free users are the first to get restricted.

Symptoms:

"ChatGPT is at capacity right now"
Slow or incomplete responses
Frequent "Something went wrong" errors

3. Region Blocks and VPN Issues#

ChatGPT is not available in all countries. If you're in a restricted region or using a VPN that routes through one, you'll get blocked. OpenAI also sometimes flags VPN IP addresses as suspicious.

Affected regions include: China, Russia, Iran, North Korea, and parts of Africa and Central Asia.

4. Browser and Cache Problems#

Sometimes the issue is on your end. Corrupted cache, outdated browsers, or conflicting extensions can prevent ChatGPT from loading properly.

5. Account and Authentication Issues#

Expired sessions, billing problems (for Plus/Team subscribers), or account flags can lock you out without a clear error message.

Step-by-Step Troubleshooting#

Follow these steps in order to diagnose and fix your ChatGPT issue:

Step 1: Check OpenAI's Server Status#

Before troubleshooting anything on your end, confirm the problem isn't on OpenAI's side.

Go to status.openai.com
Check if any components show degraded performance or outages
Look at the incident history for recent issues

If OpenAI is down, there's nothing you can do except wait — or use an alternative (more on that below).

Step 2: Clear Browser Cache and Cookies#

Open your browser settings
Navigate to Privacy & Security → Clear browsing data
Select "Cookies" and "Cached images and files"
Clear data and reload chat.openai.com

Step 3: Try a Different Browser or Incognito Mode#

Open an incognito/private window and try accessing ChatGPT. If it works, a browser extension is likely causing the conflict. Disable extensions one by one to find the culprit.

Step 4: Check Your Network Connection#

Switch between Wi-Fi and mobile data
If using a VPN, try disconnecting it (or switching to a US/EU server)
Try accessing other websites to confirm your internet is working

Step 5: Log Out and Log Back In#

Session tokens can expire or become corrupted. Log out of ChatGPT completely, clear cookies for openai.com, and log back in.

Step 6: Check Your Subscription Status#

If you're on ChatGPT Plus or Team, verify your payment method is current. Go to Settings → Subscription to check your billing status.

API-Level Troubleshooting for Developers#

If you're using the OpenAI API directly, here are the most common error codes and what they mean:

Error Code	Meaning	Fix
401	Invalid API key	Check your API key in the dashboard
429	Rate limit exceeded	Implement exponential backoff; upgrade your plan
500	Internal server error	Retry after a few seconds; check status page
503	Service unavailable	OpenAI is overloaded; retry with backoff
400	Bad request	Check your request payload and model name

Handling Rate Limits in Code#

Here's a Python example with proper retry logic:

python

import openai
import time

client = openai.OpenAI(api_key="your-api-key")

def chat_with_retry(prompt, max_retries=3):
    for attempt in range(max_retries):
        try:
            response = client.chat.completions.create(
                model="gpt-4o",
                messages=[{"role": "user", "content": prompt}]
            )
            return response.choices[0].message.content
        except openai.RateLimitError:
            wait_time = 2 ** attempt
            print(f"Rate limited. Retrying in {wait_time}s...")
            time.sleep(wait_time)
        except openai.APIError as e:
            print(f"API error: {e}")
            time.sleep(1)
    return None

The Reliable Alternative: Use Crazyrouter API#

If you're tired of ChatGPT downtime, rate limits, and regional restrictions, there's a better way. Crazyrouter is an OpenAI-compatible API gateway that routes your requests across multiple AI providers with automatic load balancing and failover.

Why developers switch to Crazyrouter:

99.9% uptime — requests are automatically routed to healthy providers
No rate limit headaches — load balancing across multiple endpoints
No region blocks — accessible worldwide
Same API format — just change the base URL, no code rewrite needed
Access to 200+ models — GPT-4o, Claude, Gemini, DeepSeek, and more

Code Example: Crazyrouter as a Reliable Fallback#

Python:

python

import openai

# Primary: OpenAI direct
# Fallback: Crazyrouter (same API format)
def get_completion(prompt):
    # Try OpenAI first
    try:
        client = openai.OpenAI(api_key="your-openai-key")
        response = client.chat.completions.create(
            model="gpt-4o",
            messages=[{"role": "user", "content": prompt}]
        )
        return response.choices[0].message.content
    except Exception as e:
        print(f"OpenAI failed: {e}. Switching to Crazyrouter...")

    # Fallback to Crazyrouter
    client = openai.OpenAI(
        api_key="your-crazyrouter-key",
        base_url="https://crazyrouter.com/v1"
    )
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=[{"role": "user", "content": prompt}]
    )
    return response.choices[0].message.content

Node.js:

javascript

import OpenAI from 'openai';

const crazyrouter = new OpenAI({
  apiKey: 'your-crazyrouter-key',
  baseURL: 'https://crazyrouter.com/v1',
});

const response = await crazyrouter.chat.completions.create({
  model: 'gpt-4o',
  messages: [{ role: 'user', content: 'Hello, world!' }],
});

console.log(response.choices[0].message.content);

cURL:

bash

curl https://crazyrouter.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-crazyrouter-key" \
  -d '{
    "model": "gpt-4o",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

FAQ#

Why is ChatGPT not working right now?#

ChatGPT may be experiencing a server outage, high traffic, or maintenance. Check status.openai.com for real-time updates. If the status page shows all systems operational, the issue is likely on your end — try clearing your browser cache or switching networks.

How do I fix "ChatGPT is at capacity" error?#

This error means OpenAI's servers are overloaded. You can: (1) wait and try again in a few minutes, (2) upgrade to ChatGPT Plus for priority access, or (3) use the OpenAI API directly. For developers, using an API gateway like Crazyrouter eliminates capacity issues entirely through load balancing.

Why does ChatGPT keep saying "Something went wrong"?#

This generic error can be caused by network issues, expired sessions, or server-side problems. Try logging out and back in, clearing cookies, or switching browsers. If the problem persists, check the OpenAI status page.

Is ChatGPT down for everyone or just me?#

Visit status.openai.com or Downdetector to see if others are reporting issues. If the status page shows no problems, the issue is likely specific to your account, network, or browser.

Can I use ChatGPT in countries where it's blocked?#

OpenAI restricts access in certain countries. While VPNs can sometimes work, they may also get flagged. For API access without regional restrictions, Crazyrouter provides worldwide access to GPT models without VPN requirements.

What's the best alternative when ChatGPT is down?#

For casual users, try Claude (claude.ai) or Google Gemini. For developers, Crazyrouter provides an OpenAI-compatible API that automatically routes to available providers — so you get GPT-4o, Claude, Gemini, and more through a single endpoint that stays online even when individual providers go down.

How often does ChatGPT go down?#

OpenAI experiences partial or full outages several times per month. In 2025, there were over 30 reported incidents. While most are resolved within hours, they can significantly impact production applications that depend solely on OpenAI's direct API.

Summary#

ChatGPT not working can be frustrating, but most issues have straightforward fixes — from clearing your cache to checking OpenAI's status page. For developers building production applications, relying on a single AI provider is a risk. Crazyrouter eliminates that risk with automatic failover, load balancing, and access to 200+ models through one API. Sign up at crazyrouter.com and never worry about AI downtime again.
