Cloudflare enabled slow.. Cloudflare paused fast.. why?

[howtoimprove]

Hi Community,

I have a strange issue with Cloudflare.

When Cloudflare is enabled the website is sometimes slow. The pages will just hang and take longer than normal to load. Sometimes the page loads and images are delayed. This also happens in Development Mode.

When I pause Cloudflare the load time is fast and back to normal.

I want to use Cloudflare so I would like to resolve.

The strange thing about it is I think it’s only happening to my fiber internet connection because when I hotspot my laptop to my mobile the website loads fast with Cloudflare enabled. Also when I try a cross browser tester the website loads fast.

Also when my mobile is connected to the fiber internet wifi and data turned off the website is slow on my mobile. When I turn off the wifi and enable data the website loads fast on my mobile. What is going on?

Is it possible Cloudflare is throttling my connection somehow? It sounds like the “rate limits” issue described in this article:

Allow Cloudflare IP addresses
https://developers.cloudflare.com/fundamentals/get-started/setup/allow-cloudflare-ip-addresses/

From the recommendation above I added these IPs to htaccess:

# CloudFlare IPv4
Allow from 199.27.128.0/21
Allow from 173.245.48.0/20
Allow from 103.21.244.0/22
Allow from 103.22.200.0/22
Allow from 103.31.4.0/22
Allow from 141.101.64.0/18
Allow from 108.162.192.0/18
Allow from 190.93.240.0/20
Allow from 188.114.96.0/20
Allow from 197.234.240.0/22
Allow from 198.41.128.0/17
Allow from 162.158.0.0/15
Allow from 104.16.0.0/12
# CloudFlare IPv6
Allow from 2400:cb00::/32
Allow from 2606:4700::/32
Allow from 2803:f800::/32
Allow from 2405:b500::/32
Allow from 2405:8100::/32
# END CloudFlare lockdown

I’ve also followed this articles recommendations:
Troubleshooting missing images
https://developers.cloudflare.com/support/troubleshooting/general-troubleshooting/troubleshooting-missing-images/

I’m not sure what else to try.

For now I have paused Cloudflare until this is fixed. If anyone can recommend anything please let me know!!

Many thanks for any advice you can provide.

I experience the same problem today with all of my sites on Cloudflare, no image content is loading at all or the content is loading extremely slow, like early modem age internet slow, making the sites completely unusable. When I switch off Cloudflare everything works fine. I did not make any changes, before everything used to run smoothly for years. Also the Cloudflare dashboard is sometimes loading extremely slow or not at all. I am in Berlin if that says anything at all.
