Troubleshooting a CloudFlare Gateway Timeout error 524 in a Flask-vue.js application

The 524 Gateway Timeout error came out when I and Manuel Guzman (MSW R&D director) were testing an ML application that took few minutes to generate results and send them back to the user. It turns out that a timeout value in CloudFlare should be increased to fix this error. We looked of course on Cloudflare documentation on Q&A blogs on how to fix the error and the answer was that it is impossible to increase the timeout (Check this StackOverflow answer). With a little bit of brainstorming, we were able to resolve the issue following Manuel's idea. In this article, I will share with you all the steps we took to tackle the 524 Gateway Timeout Error in Cloudflare.
