Privacy error with custom domain timweb.com.ar

Site name: incomparable-mousse-9653a1
Original site url: incomparable-mousse-9653a1.netlify.app

I have a domain at donweb.com and I put the DNS from netlify. I also have a professional email service at donweb.com and I set it up in the netlify DNS Zone as the tutorial from my provider told me to do.
At first the SSL certificate had no problem, but then I logged in and got a privacy error.
NET::ERR_CERT_COMMON_COMMON_NAME_INVALID

I searched the internet and they told me that I had to renew the certificate in the domain settings of netlify. This worked when I tried it but now I logged in again, after a few hours, and the same error appears again.

Domains pointed to the site:
timweb.com.ar
www.timweb.com.ar

What is the problem?

Hi there, @LeonelAlcazar :wave:

My apologies for the delay, and welcome to the Netlify Forums! It looks like it has been a few days since you posted this-- are you still receiving the same error message? Please let me know! If you are, I can look into this further for you.
