URGENT — Wildcard SSL certificate expires in 6 days, external Cloudflare DNS

My site is streamlinestrategygroup.netlify.app with custom domain streamlinestrategygroup.com. DNS is managed externally by Cloudflare. My certificate expires June 24, 2026 — 6 days from now. I am getting this error: SniCertificate::CertificateValidationError: Unable to verify challenge for *.streamlinestrategygroup.com: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.streamlinestrategygroup.com. My A records are set to 75.2.60.5 with DNS Only (no proxy). Please switch me from a wildcard certificate to a standard certificate for streamlinestrategygroup.com and www.streamlinestrategygroup.com only. Thank you.
