If you really started with HTTP:// then it looks like Chrome has switched it to HTTPS. Probably because an HTTPS connection is setup but with an invalid cert. Your cert has a name for *.prod.phx3.secureserver.net from Starfield.
Chrome has various settings to try to be more secure.
You could use the Advanced option on that screen to ensure it's the cert you setup and proceed anyway until you can replace it with a valid one.
OR, try a different browser.
OR, reconfigure your server so it does not have a valid HTTPS connection.
Thanks Mike. Your input helped me lot. Sometimes, following information may be helpful for @griffin or another volunter as seen in the following attachement. As you can see, I was able to get certificates for subdomains of mv.anura7.ca and promo.anura7.ca.
I will make an attempt again after 2022-11-09T05:11:44Z: and keep you posted.
So, here's the problem. For the addon domain names, you want the $dataDirectory (line 18) to be "../../CertSage" so that your keys aren't available on the internet via anura7.ca/CertSage/some.key. For the primary domain name, you want it to be the default "../CertSage". Notice on the lefthand side of your File Manager screenshot that there's a CertSage folder right below .trash. That's where the cert and key for your primary domain name got saved. Once you change the other copies of the CertSage script as I've instructed above (and to make it easy you can just copy and paste a changed copy to the webroot directories of all your addon domain names), your certificates and keys for ALL of your websites should appear in that CertSage folder below .trash. That means they'll be overwritten each time you run CertSage from any website (though the account keys will be reused, which is by design). If for some reason you wish to use separate data directories for each site, you can simply change "CertSage" in the $dataDirectory variable to any name you like.
Thanks Griffin, for your time to explain it in detail.
I took the relevant copies of from /CertSage under .trash folder to copy to the domain of Anura7.ca under the relevant sections of SSL/TLS. Managed to install the certificate.. https://anura7.ca worked well. When I requested the certificates, I have mentioned only anura7.ca without www.anura7.ca. So, for me to enable HTTPS Redirection, I will request again after November 11.
You guys are awesome. Instantaneous, replies. Thanks again Regards Anura
