I am trying to point a wildcard subdomain (let's say *.subdomain.domain.com) to a cloudflare worker (let's say myworker.accountname.workers.dev) but i am not able to visit the site and getting some error of TLS protocol mismatch and CIPHER mismatch. So can anyone help me out to solve this issue. This comes only when i use wildcard in simple case without i am able to visit the site.

You'd need ACM (Adv. Cert Manager, $10/mo sub) to do a wildcard, as you'd need a wildcard certificate for *.subdomain.domain.com

And also when i setup this DNS record i was able to visit the site for few times and then it stopped working. What can we be the reason for this ?
