I'm sorry to hear that you're experiencing issues with Cloudflare gateway errors. While I don't have real-time system status updates, the 504 Gateway Timeout error typically indicates that a server upstream from Cloudflare did not respond in time. This could be a temporary issue affecting multiple users. I recommend waiting a few minutes and then trying again. If the problem persists, please reach out to support for more detailed information on the current status and any widespread issues.
