Hummingbird and Cloudflare not working together

Hi @minkerr

I hope you are doing good today.

On the Cloudflare side, could you whitelist all our IPs and see if this helps:

Hi Kris,

I gave that a try but it didn’t work. I keep receiving the same error I mentioned. Any other suggestions?

Hi @minkerr

Could you please go to WordPress > Tools > Site Health when Cloudflare is enabled and confirm if any issue is being reported there?

Confirming that there are no Cloudflare issues being reported under the Site Health.

Hi @minkerr

I hope you’re well today!

Please check two other things:

1. with both Hummingbird and CloudFlare active (so case that gives you error) are you able to successfully run

– external PageSpeed insights test?
– Lighthouse test (performance category) from Chrome browser?

2. is there “under attack” mode enabled in CloudFlare? (see here). If yes, it is very likely affecting the scan/test so see if it works fine with this mode disabled, please.

Best regards,
Adam

Hi Adam,

Thank you, I’m doing well. Hope you are too. My responses are inline below.

`1. with both Hummingbird and CloudFlare active (so case that gives you error) are you able to successfully run

– external PageSpeed insights test? This test won’t run for me
– Lighthouse test (performance category) from Chrome browser? This runs great in chrome.

2. is there “under attack” mode enabled in CloudFlare? (see here). If yes, it is very likely affecting the scan/test so see if it works fine with this mode disabled, please. No, the “under attack” mode isn’t turned on at all but I found that if I disable the security completely Hummingbird will run, so not sure if that helps at all?

Hi Adam,

Hope you’re well! I wanted to give you a quick update that I figured out the issue, both Rocket Loader and Railgun had to be shut off in Cloudflare in order for Hummingbird to work.

I’m all set for now.

Hi Adam

would you please confirm, is there a problem re Hummingbird / Rocket Loader, Railgun?

Thanks

Hi @minkerr

Thank you for response!

If external PageSpeed test doesn’t run for you as well then it’s quite likely related as Hummingbird is using their API “under the hood”.

If “disabling security completely” helps, then it’s most likely due to our (or Google, in which case we can’t do much about) IPs being blocked or timed-out.

Please start with making sure that our IPs are not blocked by any security tool/firewall neither on you site/server, nor at CloudFlare. You’ll find our IPs here

https://wpmudev.com/docs/getting-started/wpmu-dev-ip-addresses/

and the important once in this case would be those under “WPMU DEV Site” and “WPMU Scan” section.

However, this may not be enough, I’m afraid. You may also need to review CloudFlare settings (especially firewall) to make sure that nothing is blocking requests from Google too (unfortunately, I don’t have and cannot have any list of their IPs as there’s no such reliable list around).

@cytracon

I don’t have simple answer to your question about Rocket Loader because Hummingbird – if it has Asset Optimization enabled – and Rocket Loader both perform optimization of site’s assets and whether this causes conflict or not is quite individual to the site. I can tell from my own experience that it often is better not to use both at once but if you are experiencing issues with this, please start a separate ticket of your own and we’ll assist you there.

Kind regards,
Adam
