Quick Troubleshooting Checklist for Common ChatGPT, Claude, Gemini, and Midjourney Errors

After using AI tools for a long time, the most annoying thing isn’t not knowing how to use them—it’s when they suddenly hit you with “No permission,” “Invalid key,” or “Connection failed.” I keep switching back and forth between ChatGPT, Claude, Gemini, and Midjourney, and I’ve run into so many pitfalls I could recite the error messages by heart. The checklist below follows the idea of “most common, fastest to verify.”

When You See an API Key Error, Don’t Rush to Blame the Model

No matter whether you’re using OpenAI, Anthropic, or Google’s interface, a wrong key / no permission / exhausted quota can all look very similar.

• Confirm the key has no extra spaces and wasn’t pasted into the wrong environment (using a test key in production is the most common)
• Check whether the project has overdue payments or has hit a usage limit
• Make sure the server time isn’t drifting—some signature validations will directly label you as an “illegal request”

Network Connection Issues Are Usually Caused by Region and Routing

Claude, Gemini, and ChatGPT may occasionally show “the website opens but requests time out.” Usually it’s not that your computer is broken; it’s an unstable route or a regional policy blocking part of the path. In my experience: under the same network, try your phone hotspot and your broadband once each—you can quickly pinpoint whether the problem is “this network” or “this account/region.”

Midjourney Generation Failures Are Usually Not a Prompt Problem

When Midjourney errors out in Discord, many people’s first reaction is to change the prompt. More often, though, it’s because channel permissions are wrong, the bot is glitching, or you’re stuck waiting too long in peak hours. Sending it once in another channel or retrying with a different command is more effective than endlessly tweaking words.

If a Local Plugin or Bot Reports Dependency Conflicts, First See What the Package Manager Is Yelling About

Some plugins that connect to large models will run into dependency/directory issues like ETARGET, ERESOLVE, and ENOTEMPTY. Don’t brute-force it—follow the error message to align versions, clean the install directory, and reinstall. The success rate is often higher than the “reboot solves everything” approach.

How to Avoid Detours

Organize your error screenshot, request parameters (without the key), and network environment, then cross-check official docs or community FAQs—you’ll be much more efficient.
