Www website reachable, non www site is not reachable

Hey,
I have a website hosted on Netlify https://preview-sightseeingride.netlify.app/. I have set a costum domain which is sightseeingride.com and www. is the primary domain. Netlify handles redirect from sightseeingride.com to www.sightseeingride.com. Though it is not working and I cant renew the SLS certificicate, see error below:
SniCertificate::CertificateNonvalidError: Unable to verify challenge for sightseeingride.com: 75.2.70.75: Invalid response from http://sightseeingride.com/.well-known/acme-challenge/LfWWOEuuYorsTEZewItOcmYW20BfWXtZEn-XZTmO7VM: 500

I handle the DNS Setting externaly(at loopia) and asked the provider if they can check if anything is missing or wring in the settings. Everything seems to be correct. The domain is pointing to netlify domain.

I read through the docs and similar posts here. But the solution from there don’t work for me.

Could someone from the support team, check if there is anything unusual going on or if I miss something here?

Thank you very much in advance!

@sightseeingride How do you have your apex configured with loopia?

The Netlify documentation is here:
https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/#configure-an-apex-domain

As per the documentation people usually set 75.2.60.5

For your domain I see multiple A records:

You probably want to remove the other records.

Fixed!

Thank you very much for the fast answer and solution! I asked loopia again but specifically about the A records and they said these records are probably old ones.

I deleted the old A records, only kept the 75.2.60.5 and could renew a SLS certificate under the domain management.

Now the website is reachable via www and non-www and is directing to the www version.

Thanks for the fast reply, wish you all the best! :smiley:
