When 103 Early Hits is enabled the Cloudflare Speed tests fail to run. After about 16 seconds the test ends with all screenshots in the test being blank. Page speeds in this tool were under 0.5 seconds before.
I am aware this is in beta. I’m know how CF is creating the headers and I’m familiar how to use cURL for diagnostics. The problem isn’t the headers itself, its that the Speed Tool in Cloudflare is getting a bug when it encounters 103 headers in the response.
I just wanted to make this pose here so that someone at CF can look into it and fix the tool. At the moment I have to go and disable the 103 Early Hints feature each time I want to run the Speed test tool in Cloudflare. Given its a Cloudflare Tool, I would have thought that Cloudflare would have tested this beta feature is compatible with all their existing tools prior to releasing the public beta.
It’s not a big deal, I just want to make sure somebody is aware of this bug and it’ll get looked at. I didn’t see it on your known bugs page.
