How to Fix Claude AI Internal Server Error

November 19, 2025 - For instance, if an API endpoint is misconfigured, access tokens are expired, or the hosting platform experiences downtime, it can impact your ability to interact with Claude. These problems may show up as internal server errors, even though the core Claude AI system may be operating.

r/Anthropic on Reddit: 500 internal server error - Internal Claude.ai API for artifacts

July 18, 2025 -

Guys, I'm sorry if this shouldnt go here but I dont really know what to do, I bought claude pro 2 days ago just to test artifacts that interact with the Claude.ai internal api and it just doesnt works, artifacts all return empty json errors and claude sonnet says the api is returning a 500 error, havent even been able to test artifacts, all status reports say everything is running, the connector and functions for artifacts its enabled, is this expected behaivour?, its with the window.claude.complete() api

r/ClaudeCode on Reddit: Claude Code Max x5 ($100) – API Error 500 “Overloaded”

September 24, 2025 -

Has anyone else been running into this with Claude Code Max x5 ($100 plan)?

I keep getting:

API Error: 500
{"type":"error","error":{"type":"api_error","message":"Overloaded"},"request_id":null}

This usually pops up when I’m working in Claude Code and trying to run requests. For something that costs $100/month, I didn’t expect “overloaded” errors like this.

Is this happening to others?
Is it a temporary Anthropic server capacity issue?
Or am I hitting some hidden rate limit even though I’m on the Max x5 plan?

Would appreciate any insights or workarounds from people who’ve faced this. Thanks!

r/ClaudeAI on Reddit: API calls getting a lot of errors. Anybody noticed the same?

March 11, 2024 -

Hey guys, I've been getting a lot of errors lately when working with the API. Mainly I get [500] Internal server error and [529] Overloaded. Does anybody encounter the same, does anybody have any suggestions for a fix or are the servers just that unstable? Unfortunately this is not allowing me to work at all.

I get more error and latency seems worst than 2 weeks ago when i look at my log (10 000 token input, 500 output, 8-10 seconds 2 weeks ago, 15-20 seconds now) Probably server is unstable. I hope it get fix because sonnet 3,5 works so well for what I do! Or that a competitor announce a new model so anthropics is less crowded!

Seems to be an ongoing issue recently. I use the API through Open Router, and they have a live chart with request fails. Noticed issues since 2 weeks ago that's intermittent.

You can’t. I have the same error, Anthropic needs to fix it… again

500 Error with Anthropic Claude 3 Opus model on Vertex AI · BerriAI/litellm · Discussion #3141

April 18, 2024 - I realize that support for the Claude 3 Opus model on Vertex AI Model Garden is still very new, so I took the opportunity to test it out. Unfortunately, I kept hitting this 500 error. A service account with the "Vertex AI User" role is assigned to the GCP Compute instance that this is running on. {"error":{"message":"VertexAIException - Error code: 500 - {'error': {'code': 500, 'message': 'Internal error encountered.', 'status': 'INTERNAL'}}\nmodel: vertex_ai/claude-3-opus@20240229\n","type":null,"param":null,"code":500}}
