For roughly the last week I’ve been unable to access builder.io via Chrome. I’ve tried on a Windows PC, Mac and an Android phone. Every time I attempt it I get a too many redirects error in the browser. It also appears to be affecting Edge and Arc browser as well. Firefox seems to work. I’ve asked a couple of colleagues to check and they are having the same issue.
Builder content link
Detailed steps to reproduce the bug
Try to access the builder site in Chrome.
I’ve also tried cURL. If I run it with only the URL as a param then I
But if I include the same parameters that the Chrome request does then the request fails.

I went through each of the headers and removed them one by one. It seems that the issue may be with the accept header. If I remove that one, I get actual HTML again.

Unfortunately, we are not able to reproduce this issue on our end. Would you be able to confirm if you and your team using any VPN? Also, not sure but could this be due to your location?
I’ve not been using a VPN. I’m based in the UK near Manchester and have been connecting over my home broadband connection. I’ve tried on my mobile phone data too but it returns the same error. I’ve not been using a VPN.
I’ve just asked a friend near London to try and he also gets the error.
Further update, I’ve had some more people try. One is based in Canada, the page loaded fine for him too, but when he used a VPN to the UK and tried again he also got the too many redirects error.
The reverse works for my UK friends with VPNs. Inside the UK the home page won’t work, but if they VPN to another country the page will load without issue.
If I use a link to another page that isn’t the root, then that page seems to load. Such as the pricing or docs pages. If I then click the header link to the home page, it will load as well, but as soon as a reload the page it will break.
We’ve successfully replicated the issue while using a VPN based in the UK. I’ve escalated this matter to our development team for a thorough investigation. Rest assured, we are actively working on resolving this issue and will keep you updated with any findings or solutions.
Thank you for bringing this to our attention, and your patience is greatly appreciated.
I’m pleased to inform you that the issue you reported should now be resolved. Please take a moment to check, and if you encounter any further difficulties accessing the Builder.io landing page, don’t hesitate to reach out and let us know.
