How to increase Cloudflare Load Balancer timeout?

Hi All,

We recently started to use Cloudflare Load Balancer with 3 pools to enable proximity based traffic steering.
Everything worked as expected, except that in some requests are cut off with gateway-timeout if backend processed it slowly (say > 100s).

We are optimizing our backend, but at the meantime, it would be beneficial if we can increase this timeout somehow.

How do we know it is cloudflare:
well the lengthy request could complete normally when hitting the backend pools directly, timeout only happen when we use the load-balancer domain name. So we figured probably it is some hidden setting that we are not aware of.

Any help on this will be greatly appreciated!


Hi Chang,

Enterprise customers can change the Proxy Read Timeout for their zone using the Cloudflare API. This is the only way to do it as far as I know, so if you’re not on the Enterprise plan I’m afraid you’re out of luck.

I hope this helps :slightly_smiling_face:


Thx Albert!

That’s very clear I will look into it.
