AWS Route 53 subdomain connected to AWS Lightsail suddenly fails to resolve

Question

About a few weeks ago, I linked my Lightsail Wordpress server to example.mysite.com using AWS Route 53.

Today, I added a security certificate by using sudo /opt/bitnami/bncert-tool . After doing this, the site worked fine and now I had a security certificate.

Then about 5 minutes later, I noticed that visiting example.mysite.com would return a browser error ( This site can't be reached ). Fortunately, visiting the server IP would still work.

I tried running sudo /opt/bitnami/bncert-tool again, but it complains that example.mysite.com doesn't redirect to the server IP, even though Amazon Route53 says so.

Interestingly, all my other AWS Route53 A Records that aren't connected to AWS Lightsail work fine.

I still tried reaching example.mysite.com for 10 minutes, but it didn't work. I tried looking up this error online but that also didn't return anything I needed. Does anyone know how to fix this?

Answer 1

The issue appears to have been some sort of glitch (which was out of my control).

Occasionally, example.mysite.com will not work, but reloading the page usually fixes it.
