Cname Already exist

Hello everyone ive seem to be having an issue.

So ive added my first domain from Porkbun and created a tunnel and it works well

I have a second domain and I want to point to to a service within my home but I get an error .

> Error: [An A, AAAA, or CNAME record with that host already exists]( For more details, refer to

unless a host with a subdomain radio.consolacast.xyx
is added then it works.


Can someone shine a light on what I could be wrong I dont know how I could fix it.
