From Cloudflare to Fly.io - First app with custom domain

[Recall45]

Hey guys, is my first time that im using fly.io to host one of my apps facing the public internet. Previously i was using cloudflare to host my domain.

So I followed the instructions at Custom domains · Fly Docs - the domain got verified, all green and then start receiving a [ERR_SSL_VERSION_OR_CIPHER_MISMATCH]

Check the docs and apparently it doesnt work that i have two TLS certificates at the domain or something like that.

So I went to my namecheap panel, changed the DNS hosting from the cloudflare servers to the basic namecheap dns and repeat the process.

Copied the A, AAAA, CNAME records, all green but still when I visit the domain got “This site cant be reach”

Has anyone faced a similar situation? If so what do you do to solve this issue?

Woop, solve it.

So what i did was go back to cloudflare, delete the CNAME, A, AAA records and wait… not sure why the cloudflare records still caused trouble despite moving the dnsserver to name cheap. But, that work for me.

Dont forget to add the CNAME www. [YOUR DOMAIN] record at namecheap too, otherwise you will get a DNS_PROBE_FINISHED_NXDOMAIN error
