Worker rate limiting when using custom domains

Hey guys, I’m getting rate limited (429/1015) on my custom domains on my worker, I used to have the same problem on the worker but after contacting support a few months back had resolved it on the worker, however it has resurfaced when using custom domains.

I’ve contacted support via a ticket a few days ago, and I’m still waiting on a reply back, this is the ticket number if someone could look into it for me #2446495

Thanks
