You need to renew your certificate.

yes it is clear, but there is a misunderstanding for me, the SSL works for main domain , but does not work for first sub domain, should i renew it via crypto page ? in which part ?

You are not proxying that beta record, hence it does not hit Cloudflare but your server directly. Consequently it does not use Cloudflare’s certificate. You can either proxy it and downgrade your security to Full instead of “Full strict” or simply renew your certificate.

I would not advise the former though and recommend to go with the latter approach.

so for renewing , the solution is in Crypto page > edge certificate > upgrade ?

No, you need to renew the certificate on your server. That is completely unrelated to Cloudflare.

So I have to renew it by Lets encrypt authority ?


Thank you for your response,
Then how can I change SSL Certificate of subdomain that it uses Lets Encrypt to Cloudflare SSL Certificate,???

Cloudflare is still not involved here, you need to renew your server certificate.

can you describe more, what do you mean by “Cloudflare is still not involved here”?
so I have to make changes in AWS ( my website hosted in AWS) ?

I can not use Cloudflare SSL certificate for ???

You have a certificate on your server. That certificate has expired. You need to renew that certificate.

Cloudflare has nothing to do with that, unless you have an origin certificate issued by them in which case you’d go to the control panel and have that certificate issued. You will still need to configure it on your server though.

This is all something you need to fix on your server.
