SSL Certificate Issues/"This site can’t provide a secure connection" ERR_SSL_PROTOCOL_ERROR

Hello!

I’m having difficulties with getting my Netlify-hosted site secured (custom domain: milestoneautomation.com; netlify URL: milestoneautomation.netlify.app). It’s been working fine for the last year or so (since it was initially hosted back in Nov. 2023), but seemingly some time this month (December), its connection has been deemed “not secure” by Google/Chrome.

I’ve been going back and forth between the Netlify domain management panel and IPOWER (where the DNS and nameserver records are) to fix the issue. Right now, I’m trying to renew my Let’s Encrypt certificate through Netlify but I’m getting this error.

Thoughts?

For the record, I’d like to keep the DNS records on IPOWER if possible, for company reasons.

Hey there, this challenge is automatically created during a DNS process. I’m wondering if your second A record might be conflicting – is this record necessary for you?:
milestoneautomation.com has address 99.83.190.102

Thanks!

I’m not quite sure… I only have an A record for 75.2.60.5 on IPOWER at the moment, not one for 99.83.190.102. I’ve tried having one for both in the past to no success either (might’ve gotten a different error though, I’ll let you know).

To clarify, here are the main website-related records I have on IPOWER (added back the 99.83.190.102 one):

CNAME WWW milestoneautomation.netlify.app
CNAME _acme-challenge milestoneautomation.com.letsencrypt.vdeck.eigdyn.com/

To use external DNS, you’ll want the following records:

Type Name Value
A @ 75.2.60.5
CNAME www milestoneautomation.netlify.app

You should not have the second A record pointing to 99.83.190.102. You also do not need the _acme-challenge record in order to provision an SSL certificate with Let’s Encrypt.

Alright, I’ve removed those 2 records, annnnnnnnnnnd the site’s secured now!

Wow, thought I woulda already tried this combo of records, but thank you so much!
