Website doesn't connect anymore. Quite urgent to get it back up

Hello,

Recently I received email at work the our website has stopped working. It seems that at least on deploy nothing has broke because it would say it in the logs. When going to the website using www.pehutec.com it keeps complaining about privacy error and certificate doesn’t seem to be valid and it should auto renew. When I try to renew the certificate following error will pop up.

This address however still works normally

https://pehutec.netlify.app/

but out domain address does not work anymore

www.pehutec.com ← this is also set as the primary domain & pehutec.com

DNS verification failed

Our website has worked normally until some point this month. Also I checked the DNS settings and they should be correct.

Your DNS is indeed not pointing to Netlify:

dig A +short pehutec.com
167.172.139.120

Please refer to: Configure external DNS for a custom domain | Netlify Docs
