I've been having some ongoing issues with getting a Let's Encrypt certificate to work consistently on our network. The last time we gave up because of problems and had to export the site. This time I managed to get it to work but having issues with Chrome.
I think the problem has to do with the subdomains not having an SSL certificate but I can't be sure. Our system doesn't allow for a wildcard certificate when using mapped domains. The most recent launch I got the SSL to work on most browsers but after I logged into the website Chrome is now throwing a Not secure.
I'm looking for some guidance and requirements for have a network with stable SSL on mapped domains on a network.
