Ssl regeneration issue on GCP Load Balancer with Cloudflare host record

I have my backend hosted at GCP on Cloud Run (Container based), that has Loda Balacner. In order to access it I need ssl certificate, google keep searching endpoint which dns is on cloudflare on Proxy mode thus it doesn’t detected.
What is the best way to avoid this issue, removing proxy record and keep it A record or what? My production was down becuase of this for hours as google takes a lot of time to generate and install certificate on load balancer.

For instance if I create new ssl certificate for other records also it also takes a lot of time to generate certificate on Cloud Run manage domain.

Thanks,
