Hi, @user-at, and welcome to our Netlify community site.
The I’m showing this SSL certificate was created around
Thursday, November 28, 2019 at 9:18:30 PM Pacific Standard Time. This comes from the certificate itself (screenshot from Chrome while browsing the site):
So, I don’t think the SSL certificate expired. It is certainly possible that there were SSL failures but, if so, it doesn’t appear the certificate itself was the root cause.
To troubleshoot what did occur, it would help us to know more about the HTTP requests which resulted in SSL errors.
x-nf-request-id header in the HTTP response would help us to track down the answer. However, the connection is most often closed when the SSL connect cannot be established and when this happens no response headers are sent.
x-nf-request-id header isn’t available (and I’m guessing it isn’t) then the following details would be helpful:
- the day, time, and timezone when the HTTP request was made
- the IP address making the request
- the IP address which responded
- the URL being requested
Would you be willing to please send us those details?
I’ve made sure you can send private messages (PMs) in case you do not want to share these details publicly.
Also, if there are other questions about this, please let us know.
