Flask - HTML file Changes not reflecting in browser (webapp)

I have a Flask App. There is a module where I update the HTML file in ‘templates’ by taking data from Google Sheet. I could see that the the html file is updated when I see from shell. But I don’t see the changes in the Browser. It still shows old code. I had the same code hosted in replit a while back where this functionality was working fine.
Any help would be appreciated.



It’s hard to offer any advice without details. A couple things spring to mind:

  • Render instances have ephemeral filesystems, so any file created after it boots will be lost on the next restart (e.g. next deploy, manual restart, free spin-down, etc.) - if you to persist an uploaded/generated file beyond restarts you’ll need a Render Disk or external store.

  • Maybe there’s some caching somewhere?

If you could share some specific details that may help us troubleshoot it with you, e.g. any logs/errors/output, specific URLs, service name/ID, reproduction steps, etc. If you don’t want to share these details on the community forum, please feel free to raise a ticket from the “Contact Support” or “Help” links while logged into the Dashboard.
