AWS certificate manager certificate renewal

The certificate renewal process was unsuccessful due to Cloudflare configuration for our domain(Cloudflare just blocked Let's Encrypt validation requests). Approximately 7 hours ago we updated the Cloudflare configuration and it shouldn't block Let's Encrypt anymore, but we still didn't receive any requests from them, and our SSL certificate is still pending validation. Unfortunately for us, this certificate expires today, and we don't have a lot of time for that. I've tried requesting a new one, but it was also unsuccessful(certificate validation failed), and importing the Cloudflare origin certificate also was unsuccessful(import failed). I can't find any logs to debug that, and can't force Cert Manager to try to validate us one more time. Please help us.
