CNAME record exists — your subdomain must have a CNAME record pointing to redirect.referral-factory.com. Log into your DNS provider and verify this is set up correctly.
No conflicting A record — if there is an A record for the same subdomain, it overrides the CNAME and sends traffic to the wrong server. Remove the A record so the CNAME takes effect.
SSL certificate error (ERR_SSL_VERSION_OR_CIPHER_MISMATCH) — if your DNS is correct but you see an SSL error, the SSL certificate has not yet been provisioned on our end. Contact support so we can enable it for your domain.
DNS changed after a hosting migration — if you recently switched hosting providers, the CNAME record may have been lost. Re-add it and allow up to 48 hours for DNS propagation, though most changes take effect within 30 minutes.
