Will Comodo SSL work on a subdomain which points to external server using DNS zone editor? - ssl

I have a domain called qlink.co.in and I have a cpanel for this domain.
In cpanel I created a sub domain - server1.quicklink.co.in
In this cpanel in DNS zone editor I pointed this sub domain to my server1 like shown in image below -
Now I can access my http://server1 IP address. My link as http://server1.qlink.co.in/.
If I install ssl on my qlink.co.in domain which comes with unlimited sub domain option, then do I need to do anything on my server1 server or not? Will my subdomain link work with https?

SSL should be installed on domain from the server where your domain is pointing. As your sub-domain is pointing to other provider's server, you should install the SSL from that server.
It will not work, if you will install it from the server where your main domain is pointing.

Why won't my https://domain forward to www?

I have a website for my podcast built with Python / Django that is hosted on Heroku: https://dinpodcast.herokuapp.com/
I have a custom domain parked on GoDaddy, dinpodcast.com, that has a www CNAME directing to my heroku application. This works just fine: https://www.dinpoddcast.com
I wanted dinpodcast.com to redirect to the www website, so I have the following domain forwarding set up on Godaddy:
This also works great, for the most part. Now, when I enter http://dinpodcast.com, or just dinpodcast.com, both will redirect to https://www.dinpodcast.com.
Here's the problem. When I enter the naked domain WITH HTTPS, so when I enter https://dinpodcast.com into a browser's address bar, I get the following response:
Here's what I THINK is happening. My SSL certificate is provided by Heroku under their Automated Certificate Management program. So, I assume that since I don't have an SSL certificate with GoDaddy, it's timing out trying to find one before it can redirect to my www subdomain. Would this be correct? If so, is there any way around this WITHOUT buying an SSL certificate with GoDaddy? If that's not what's happening, then what is and how do I fix it?
When you create an ssl certificate in your domain do you include your root domain? Tried using this tool in your root domain and it seems that there is no ssl certificate. However the subdomain https://dinpodcast.herokuapp.com/ has one. I suggest putting an ssl certificate in all subdomain and root domain that you are using.
I also checked the root domain’s IP address using this tool and checked port 443 using another tool and apparently the port is closed. Double check your firewall and make sure 443 is open.

LetsEncrypt on Domains

I've a domain name, basecompany.com. My application is deployed on the server and the IP has been mapped with the domain name in GoDaddy domain registrar DNS settings. Also, it is https enabled using Letsencrypt which automatically refreshes my certificate after every 3 months.
Now, I purchase 5 more domains and just want to reroute those 5 domains to basecompany.com. Nothing else. These are just URLs with no application server. So, I used domain-forwarding service.
However these 5 domains are not https secured. How do I apply letsencrypt certificated within my DNS settings itself, or do I have to separately purchase a SSL certificate from them?
PS: I'm skipping my option to add the domain name in my webserver (nginx)
config file and then map the IP to my DNS of new domain names. I dont want this.
I just want to install the certificate and it should start working.

Confusion in using SSL virtualMIN and wordpress website

I have a domain (e.g.) example.com
I am using a virtual machine in a cloud having public IP. on this VM i am also using VirtualMin for shared hosting. so i have multple URLS to access different services such as email,wordpress, virtualmin console, and website address. now i need to use SSL on all these addresses however all these address does not change the sub domain. so do i need to buy wildcard (which is very expensive) or i can use simple SSL.
here are the site links that i need to encrypt.
Website https://example.com (hosted via virtualmin)
Email https://example.com/mail (hosted via virtualmin)
Wordpress https://example.com/wp-admin (hosted via virtualmin)
virtualmin https://example.com:10000 (virtualmin console)
virtualmin email https://example.com:20000 (virtualmin email console)
as you can see all these URLS has no change in sub domains rather port and landing directories are change. so do i need Normal SSL for all these links or i need wildcard ?
Thanks.
A Normal SSL will be fine for your needs, I would suggest creating a self signed certificate to test out your setup. Another tip is to look into the Let's Encrypt option as that will allow you to set up a Let's Encrypt certificate.
Virtualmin > Server Configuration > Manage SSL Certificate > Let's Encrypt
And then you will need to follow this guide:
https://www.virtualmin.com/documentation/tutorial/how-to-add-an-ssl-certificate
Once you have the SSL installed you then need to apply it to all the parts of the server via
Virtualmin > Server Configuration > Manage SSL Certificate > Current Certificate > Copy to Webmin / Copy to Usermin / Copy to Dovecot / Copy to Postfix

Installing SSL for sub domain which pointing to another server

I have domain www.xyz.com with dedicated IP,SSL for www.xyz.com is already installed and working fine.
now through plesk panel i am able to create 10 sub domains.
I have created one sub domain named subdomain.xyz.com which is pointing to totaly different server.
I want to add SSL certificate for subdomain.xyz.com.
where i have to add SSL certificate, on the the server that sub domain is pointing or i can add SSL for subdomain.xyz.com from xyz.com plesk panel.
the subdomain is pointing to solaris server
You will need to install the SSL certificate on the actual server that is responding to your HTTPS requests (meaning, the one the subdomain points to). However, keep in mind that if you have a regular SSL certificate, then the certificate would have to be issued to the specific subdomain. For example, a regular SSL certificate for example.com does not validate against sub.example.com.
As an alternative, you can purchase a wildcard SSL certificate for your domain that will cover the new subdomain and any others you add later. More info on that here: https://www.digicert.com/wildcard-ssl-certificates.htm

How to add SSL with subdomain on different server?

I have the same issue as this guy: How to add SSL to subdomain that points to a different server?
However, I have no clue how to do this.
I have purchased a Wildcard SSL and set sub.mydomain.com to the IP of the other server using DNS records (A record).
Everything is installed correctly on the main server, however on the sub.mydomain.com the SSL doesn't work.
I'm using Plesk Panel on Ubuntu 14.04
Any idea how I can make it work on the other server?
Thanks!
What error are you getting ?
No matter the subdomain is created on which server if you have certificate and private key you can install ssl on the subdomain
