| Common Causes | Server overload, deployment updates, context exhaustion. | Usually auto-recovers within 1-5 minutes. |
| Status Check | Official status page at status.claude.com. | The first place to check for global outages. |
| Backup Solutions | AWS Bedrock / Google Vertex / API Proxy. | Ensures zero downtime during critical tasks. |
What Does the Claude Code 500 Error Actually Mean?
An HTTP 500 Internal Server Error is a code returned by Anthropic's servers, indicating that something went wrong on their end while processing your request. It's a "hands-off" error—the issue lies within Anthropic's backend infrastructure, not your local setup, editor config, or API key.
Based on the request_id field (e.g., req_011CXmPyLVR6ekeW8pMBBMGD), Anthropic can trace the specific failed request, which is incredibly useful if you need to file a support ticket.
According to data from the third-party monitoring service StatusGator, the Claude API has experienced 62 incidents in the last 90 days (19 major outages + 43 minor ones), with a median duration of 1 hour and 19 minutes.
Common Causes of Claude Code 500 Errors
Reason 1: Anthropic Server Overload
As a cloud service, Claude AI has a maximum traffic capacity. When thousands of users access it simultaneously (like during peak hours or right after a major update), the servers can become overloaded, leading to 500 errors.
Recent Incident Log (February 2026):
| Date | Event | Duration | Impact Scope |
|---|---|---|---|
| Feb 3 | Service Outage | ~10 mins | Partial users |
| Feb 2 | Opus 4.5 Errors | ~6 mins | Opus 4.5 users |
| Feb 1 | Purchase/Billing Issues | Several hours | API top-up users |
| Jan 29 | Billing System Failure | Several hours | Balance and top-up features |
| Jan 14 | Service Deployment Issue | ~4 hours | Opus 4.5 and Sonnet 4.5 |
Reason 2: Context Window Exhaustion
When Claude Code's remaining context hits 0% and fails to trigger an auto-compact in time, it'll throw a 500 error. In this scenario:
- Starting a new conversation usually works fine.
- Resuming the old conversation might continue to fail.
Reason 3: Service Deployment and Configuration Changes
Anthropic's service deployments can sometimes temporarily reduce capacity. For instance, on January 14, 2026, a deployment caused Opus 4.5 and Sonnet 4.5 users to experience errors for about 4 hours, which was eventually resolved by rolling back the deployment.
Reason 4: Mixing Traffic Between Platforms
Anthropic officially warns: Don't mix Claude API traffic between Bedrock, Vertex, and api.anthropic.com. If you're switching between different platforms, you might trigger errors. Each platform is perfectly stable when running independently.
🎯 Diagnostic Tip: If you hit a 500 error, first head over to status.claude.com to see if it's a global outage. If the official status is green, then check your local environment. The APIYI (apiyi.com) platform offers multi-channel Claude API access, which serves as a great quick-switch backup during outages.

6 Ways to Fix Claude Code 500 Errors
Method 1: Wait for Auto-Recovery (Recommended First Step)
Most 500 errors resolve themselves within 1-3 minutes. These are usually brief hiccups on Anthropic's backend and often clear up faster than any troubleshooting steps you could take.
# Recommendation: Wait 1-3 minutes and retry
sleep 60 && claude # Restart Claude Code after 1 minute
Method 2: Start a New Conversation
If the old conversation keeps throwing errors, try starting a fresh one:
# Exit current Claude Code session
# Restart and start a new conversation
claude
Why it works: A new conversation can reset the state if the context is exhausted or the session state becomes corrupted.
Method 3: Update Claude Code Version
Anthropic frequently fixes known issues via version updates. For instance, the outage on January 31, 2026, was resolved by updating to v2.1.29.
# Update to the latest version
npm update -g @anthropic-ai/claude-code
# Verify version
claude --version
Method 4: Clear Cache and Sessions
Browser or local cached data can sometimes interfere with Claude's responses:
# Clear Claude Code config cache (Use with caution)
rm -rf ~/.claude/cache
# Reset session
claude --reset-session
Method 5: Check API Key and Configuration
While 500 errors are usually server-side issues, it's good practice to ensure your configuration is correct:
# Check environment variables
echo $ANTHROPIC_API_KEY
# Verify API Key validity (test with curl)
curl -X POST "https://api.anthropic.com/v1/messages" \
-H "x-api-key: $ANTHROPIC_API_KEY" \
-H "anthropic-version: 2023-06-01" \
-H "content-type: application/json" \
-d '{"model":"claude-sonnet-4-20250514","max_tokens":10,"messages":[{"role":"user","content":"Hi"}]}'
Method 6: Switch to a Backup API Channel
When the official Anthropic API is persistently unavailable, switching to a backup channel is the most effective solution.
Tip: Get multi-channel Claude API access via APIYI (apiyi.com). The platform integrates Claude models via AWS Bedrock, allowing for seamless switching when the official API fails.
Claude Code 500 Error Backup Plan: AWS Bedrock Configuration
When api.anthropic.com goes down, AWS Bedrock is the most reliable backup. Claude models on Bedrock run independently of the official API, ensuring they aren't affected by the same outages.
AWS Bedrock Configuration Steps
Step 1: Set Environment Variables
# Enable Bedrock integration
export CLAUDE_CODE_USE_BEDROCK=1
# Set AWS Region (Required)
export AWS_REGION=us-east-1
# Ensure AWS credentials are configured
aws configure
Step 2: Configure Inference Profiles
AWS Bedrock requires Inference Profiles for on-demand usage, providing better reliability and cross-region failover:
# Verify Bedrock access
aws bedrock list-foundation-models --region us-east-1 | grep claude
Step 3: Use in Claude Code
# Launch Claude Code using the Bedrock channel
CLAUDE_CODE_USE_BEDROCK=1 AWS_REGION=us-east-1 claude
