Have you also had one of those maddening moments: ChatGPT or Claude throws a 401 as soon as you call the API, Gemini suddenly returns 403, and then Midjourney gets stuck in Discord and won’t generate images. Don’t worry—I've organized the pitfalls I’ve personally run into into a “just follow this and check” checklist.
How to match the most common API errors
401 Unauthorized is most likely the key is wrong
Don’t laugh—some people actually copied an extra space into it. It could also be that the key doesn’t have enough permissions or has been revoked. When using clients like Cherry Studio, remember to check whether you switched to the wrong assistant configuration or the shared parameters used across topics.
403 Forbidden is usually region- or risk-control-related
Switching IPs too frequently, an unstable proxy, or incomplete billing information can all trigger it. Gemini and Claude are more sensitive to network environments; it’s recommended to use a fixed egress and not jump from Hong Kong one moment to the U.S. the next.
429 Too Many Requests isn’t because you’re unlucky
You’re just being rate-limited. Reduce concurrency, add randomized delays to retries, and don’t let your program spam calls like a relentless barrage. If needed, you can use solutions like an mcp gateway for unified forwarding and rate limiting.
If your local project won’t run, don’t blame the model
When installing plugins with Node, common Yarn errors like ETARGET, ERESOLVE, and ENOTEMPTY are often caused by version and dependency conflicts. Lock down your Node version first, then clear the cache and reinstall dependencies—don’t hack at the code in a sea of red error lines.
Common reasons Midjourney image generation fails
- Your Discord account hasn’t completed verification or has been risk-controlled—fill in your email and phone first
- Incorrect channel permissions—you’re sending the command in a room where it can’t be used
- The queue is too full—try off-peak hours or upgrade your plan for better stability
My own lazy-person recommendation
If you just want to use ChatGPT, Claude, Gemini, and Midjourney reliably without constantly battling keys, networks, and billing, go take a look at the ready-made hassle-free solutions on Titikey—less tinkering really does make you happier.
