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!
