Fly.io egress IPs blocked by Cloudflare?

Questions / Help
1

I’m trying to run an app on Fly.io that connects via WebSocket to a third party site behind Cloudflare. Usually this is perfectly fine, I have ran the service from my residential IP and other clouds and had no issues, but it looks like Cloudflare is specifically blocking Fly.io egress IPs resulting in 403.

On a few rare occasions I have been able to get an IP which isn’t blocked.

Is this a known thing? Is there some way to work around this?

Thanks.
