Hello I have this Setup
My domain is:
Company.com, i want to create a subdomain with https ie. portal.company.com
this subdomain only an A in DNS Records which pointed to a public IP (firewall/proxy) that forwarding to my local server (192.168.xx.xxx). I can access
portal.company.com in my intranet
Is it possible to use https on my intranet ? like accessing
https://portal.company.com from my intranet.
If by “
company.com” you actually mean a real public domain, then yes.
There are several ways to authenticate and obtain a cert.
The first choice on that path is can the Internet reach your portal server via http (port 80)?
Then which O/S does the web server run on (and version)?
Then which web server does it run (and version)?
Have a look at:

I can make it happend for my local server to reach internet
i’m using windows server 2012 R2
webserver is IIS
I managed to get my certificate onmy intranet but when i access my intranet from outside im getting an error “ERR_SSL_PROTOCOL_ERROR”
any idea what might i do wrong ?
to check your configuration your domain name is required.
Checking your domain there are older checks -
https://check-your-website.server-daten.de/?q=portal.permatagroup.com - last with Grade W, http works, https not.
But my browser says, now the url works. Rechecked the domain, again Grade W, https doesn't work.
Perhaps there is a blocking firewall so it's impossible to use online checks.
And there are some errors, missing files.
do you mean the i should enable the inbound for port 443 ?
If you want to use online checks, that's required.
Now port 443 is open - and Grade I -
but still i’m getting err_connection_reset or SSL_PROTOCOL_ERROR
btw can you access it ? https://portal.permatagroup.com
btw can you access it
That's the reason you should use online tools. Then you can test such things.
Perhaps your ciphers are too low/weak/insecure for your client:
[there are only two GREEN ciphers, but even they use very weak DH keys]
