Site uses an unsupported protocol after adding DNS record

Hello.
I need your help.
After I changed DNS of Cloudflare then my site is not working.

It’s said:

This site can’t provide a secure connection

api.mrdeveloper.nacbots.in uses an unsupported protocol.

ERR_SSL_VERSION_OR_CIPHER_MISMATCH

HIDE DETAILS

Unsupported protocol

The client and server don’t support a common SSL protocol version or cipher suite. But the same website is working at api.nacbots.in

Please check and fix help me.
Thanks for supporting.

Welcome to the community!

That’s a second-level subdomain. Universal SSL only protects the root domain and first-level subdomains.

You’ll need to purchase Advanced Certificate Manager to protect second-level subdomains or deeper.

Hope it helps!

But code.mrdeveloper.nacbots.in working fine :thinking:

@botmakerdeveloper Hello there,

It looks to me you are using a free Cloudflare edition. Cloudflare free edition does provide SSL for root domain & *.domain.
If you need SSL for multi-sub-domain, I suppose you need to upgrade or purchase. Read more at the doc

Since it isn’t proxied and therefore not going through Cloudflare.
