hello, on my website I have uploaded a logo or an image, but the changes are not reflected, even though I have already purged the cache, but when I enter my hosting in my files, I can see the logo or image that I have updated please help
May I ask you to post and share the URL example to the particular resource in a bracketed dot [.] notation with us so we could double-check, troubleshoot and provide some feedback information reagarding the HTTP cache headers? 
I wonder which HTTP cache headers are set for it.
Furthermore, may I ask you to check out what option have you got selected by navigating to the Cloudflare dashboard → Caching → Configuration → find section “Browser Cache TTL” and make sure the selected option from the dropdown menu is “Respect Existing Headers”.
Furthermore, from the same menu, click on the blue button saying “Purge Everything” to flush the cache at Cloudflare Edge, just in case.
Wait for a minute or two.
Refresh a page in your Web browser, otherwise try clearing your Web browser cache or use a different Web browser to test out again.
May I ask have you tried using a different Web browser, or tried clearing your Web browser cache?
How about using a Private window (Incognito mode) or a VPN connection if possible?
Is it the same behaviour on your mobile phone (4G LTE, mobile data, cellular)?
You could also determine if this behaviour continues even by using a “Pause” option at Cloudfalre as follows:
- Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
- The link is in the lower right corner of that page.
- Give it five minutes to take effect
- Make sure site is working as expected with HTTPS.
- Retry on Google Search Console and make sure you’ve got the file
- Upon success, un-pause
