In Proscan,
1.) I'm trying and have been trying to obtain a "lets encrypt"cert and cannot for the life of me get my port 80 to be accessible. "Failed Acquiring Certificate -3" error. I've port forwarded port 80 and port 443 and it just fails, probably blocked by my ISP. Are there any tricks of the trade to obtain a valid certificate? I did try a "self signed" certificate but the site gives me err-validity too long error. I need the https to iframe into my PHP site because of site security.
To find out if your ISP is blocking port 80, start the Web Server using port 80 then go to
canyouseeme.org and see if it's successful.
Perhaps temporarily disable any Internet Security/Anti virus software and see if that works.
{edit} Don't mess with port 443. That port uses the secured method and if you don't have a certificate yet then port 443 won't work.

} Try this if still unsuccessful. 1) Turn on the WiFi hotspot on your phone. 2) Set your computer network connection to the phone WiFi hotspot. 3) Start the web server on port 80 then try
canyouseeme.org to see if it's successful. If successful then turn off the web server and try to obtain the letsencrypt cert. again.
