502 Bad Gateway

Response code 502 means the Midjourney Discord bot did not reply within the allotted time limit. This usually happens when the Discord Gateway API or the Midjourney Discord bot is having issues.
You can check Discord status and Midjourney Discord server status channel.
Keep in mind that both links above most often will not reflect an event that has just started.
504 Job queued

Job queued. The API will not be able to track the progress of this job, although it will still be processed by Midjourney. You may want to adjust the maxJobs number to a lower value for the next several minutes.

You should not receive this error under normal circumstances unless you have specified a maxJobs parameter higher than your Midjourney subscription supports, or if you are using the Midjourney bot outside of API interactions. On occasions when Midjourney is releasing new updates or experiencing technical issues, jobs may be paused for an extended period of time. Our API will mark all jobs running over 30 minutes as failed. When Midjourney comes back online, it will attempt to complete previously paused jobs, and you may encounter a conflict if you try to submit a new job at the same time. Although this happens very rarely, we have decided to add an extra layer to ensure such cases are detected.

    "error": "Job queued",
    "jobid": "<jobid>",
    "status": "failed",
