Gonzalo, I was having problems with communication from a Chrome Extension to my apache server. Some of the headers were getting mangled (only coming from the server back to the extension). I have tried everything! In my attempt to figure out what is going on, I actually made the instance inoperable. So I had to delete it (I didn't have a snapshot) and start over, which I did. That was a few weeks ago.
In yesterdays attempt to figure out what is wrong, I decided to install a new cert instead of Let's encrypt. I think a non self signed one would be better. I was working with Digicert support. There is something called www.example.com that we can't find. I was told on Let's Encrypts site that it might be a bitnami placeholder. Can you tell me where this is located so I can delete it?
Certificate does not match name www.rdsubstantiation.com
