ERR_SSL_VERSION_OR_CIPHER_MISMATCH when access neo.is-a.dev on browser

[phantonducthang]

My domain: "neo.is-a.dev"
Hey man, i already connect my domain to gitbook.io to make a docs site with a CNAME record. But when i trying to access to my website. It give me a problem "ERR_SSL_VERSION_OR_CIPHER_MISMATCH " . I also try to access my website on my phone and find ways to fix, but both of them are not working for me.

CNAME record: 64342fb9f8-hosting.gitbook.io

I checked my CNAME on dnschecker.org too. CNAME is working.

How to fix it.
Thanks for your help : )

Excuse me! Now i found the problem is at cloudflare proxy. I asked on Gitbook.io docs, they have problem with Cloudflare Proxy, I must disable cloudflare proxy, so can you disable cloudflare proxy for my domain? plz... 🥺

I'll very happy with your help
Thanks
Love your team : )

we don't use cloudflare?

[phantonducthang]

Hmmm.... I don't know. How to fix this problem😱😱

[MaskDuck]

have gitbook said that custom domains setup is live?

[phantonducthang]

Yes!

Your team doesn't use cloudflare, but they said me this. What is the problem?

[phantonducthang]

Maybe the problem is at SSL. I'll reconnect this domain. Thanks for your help.

yippee! The problem is FIXED 😊. The real problem is SSL. Gitbook forgot to create an ssl for my website, so I get ERR_SSL_VERSION_OR_CIPHER_MISMATCH when access neo.is-a.dev on browser. Now it's working perfectly. I just reconnect the domain with gitbook. Thanks!
