Redirection Problems https://mydomain.com --> https://www.mydomain.com

Hello, i hope you are doing well,

Here is my inquiry :

if i request https : // mydomain . com redirects --> DNS_PROBE_FINISHED_NXDOMAIN
if i request mydomain . com redirects --> https : // www . mydomain . com and works well
if i request www . mydomain . com redirects --> https : // www . mydomain . com and works well

So i would like to fix https : // mydomain . com redirects --> https : // www . mydomain . com and works well

Here is my config :

I am using a thrid-party website that i redirect my domain to, it’s called kartra, so i basically have this as my DNS Zone Record :

TYPE ------- NAME ------- CONTENT -------------------- TTL ------ Proxy Status
CNAME ---- www --------- mydomain . kartra . com ------ Auto ----- DNS Only

That’s all i have, i am wondering if i have to add TYPE A Record but i don’t know where to point it.

For redirection here what i have :

*mydomain . com/

Forwarding URL (Status Code: 301 - Permanent Redirect, Url: https : // www . mydomain . com)

mydomain . com/

Forwarding URL (Status Code: 301 - Permanent Redirect, Url: https : // www . mydomain . com)

Everything else hasn’t been touched.

Well i hope you can help, let me know if you need any further information.
