I have one nodejs web app on ibm cloud: MYAPP.eu-de.mybluemix.net.
I want it to be reachable over https on https://MYSUB.MYDOMAIN.IO
I own MYDOMAIN.IO, and added this CNAME entry in my dns provider: MYSUB.MYDOMAIN.IO. 0 CNAME MYAPP.eu-de.mybluemix.net.
I purchased a certificate for SUB.MYDOMAIN.IO added the domain in my organisation, and uploaded the certificate. Note it is not a wildcard. I read that long ago bluemix only accepted wildcards, but I could upload my single certificate without issue.
I also added the route to the app so I have 2 routes in the settings, both with the padlock green:
MYAPP.eu-de.mybluemix.net
MYSUB.MYDOMAIN.IO
After all this, when I navigate to https://SUB.MYDOMAIN.IO, I end up on the app page (redirection working), BUT I get the security warning because the certificate is still the one of bluemix, not mine.
What am I doing wrong???
ok got it sorted after swimming in an ocean of outdated ibm doc, I found that to use custom domain, the DNS config should be a CNAME to a specific domain name.
in my case, not MYAPP.eu-de.mybluemix.net but MYAPP.eu-de.cf.appdomain.cloud
This URL was always there in the list of available domain, but it was hard to find its use.

I have a cloud front app with domain xyz123.cloudfront.net.
This CloudFront is then mapped to domain sub1.mydomain.com. For this, I followed these steps.
Added SSL through AWS CloudFront pannel to *.mydomain.com
Added A Alias record in Route 53 to xyz123.cloudfront.net
This makes sub1.mydomain.com work perfectly over SSL.
Now, I want to allow my users to use their own domain (eg sub1.userdomain.com) to access the app.
This is similar to what UptimeRobot allows in its public status pages.
What I tried, but not working
Added CNAME to sub1.userdomain.com pointing to xyz123.cloudfront.net, I get SSL Error
Added CNAME to sub1.userdomain.com pointing to sub1.mydomain.com, I get SSL Error
Added CNAME to sub1.userdomain.com pointing to xyz123.s3-website.ap-south-1.amazonaws.com (S3 Static Hosting URL)
Question
How does UptimeRobot (or GitHub Pages) allow users to add a custom domain to their status page over SSL
What is the prerequisite to make this happen?
From https://github.blog/2018-05-01-github-pages-custom-domains-https/:
We have partnered with the certificate authority Let’s Encrypt on
this project. As supporters of Let’s Encrypt’s mission to make the
web more secure for everyone, we’ve officially become Silver-level
sponsors of the initiative.
Github pages create a single certificate, from Let's Encrypt, for both your custom userdomain.com and YOURNAME.github.io. This is possible with a SAN certificate (Subject Alternative Name, https://support.dnsimple.com/articles/what-is-ssl-san/).
You can't associate more than one SSL certificate to a CloudFront distribution but ACM (AWS Certificate Manager) supports up to 10 subject alternative names. To mimic Github Pages you have to know the user domains beforehand or create a new certificate each time you add a new domain to replace the old one.
Unfortunately, there is no way to add more than 10 custom domains to a SSL in AWS.
Which is a prerequisite to having a custom domain to your cloudfront.
Hence, a workaround this could be as below.
1. Create a S3 single bucket which hosts your code
2. Create Multiple Could front distributions connected to single S3 Bucket
3. Then, add custom domains to these cloud front.
You will also need to think about CORS settings in your API of the app to allow requests from these custom domains.
In Heroku, my domain name for www.[somesite].com shows an ACM Status of "OK".
I also am using automatically managed SSL.
On Google Domains, I have a CNAME for www pointing to the DNS target.
I also have a synthetic record forwarding # for .[somesite].com to https://www.[somesite].com, with Temporary Redirect, Do not forward path, and Disable SSL.
If I use "Enable SSL" I get an error saying that:
The SSL Certificate for this domain hasn't been created yet.This process may take up to 24 hours to complete.
However, the site does not work. I do not know why Heroku shows that it does nor why it gives a ACM Status of OK.
I have been beating my head against this for several hours and have no idea what to do. Anyone have an idea?
Updated 2021
The following guide will help you to set up a website with SSL and forward all versions of your site to the appropriately secured site (https).
(Heroku) Deploy the site on Heroku (either with CLI or Github integration)
(Heroku) Upgrade to the "Hobby" Dyno (for $7).
(Heroku) Add SSL by going to Settings -> Configure SSL. Choose "Automatically".
(Heroku) Add a domain (on heroku.com) by clicking "Add domain". Be sure to use www in the domain name. So the Domain Name text field would be "www.example.com".
(Google Domains) Add a Custom Resource Record
Name: www
Type: CNAME
TTL: 600
Data: URL from Heroku
For example, behavior-apple-eh2cfqgjkiop23q1wvd4372b.herokudns.com.
(Google Domains) Add a Synthetic Record
Subdomaine Forward
Subdomain: #
Destination URL: https://www.example.com
Permanent Redirect (301)
Forward path
Enable SSL
(Google Domains) If you are using a domain that requires DNSSEC (such as a .dev domain), enable DNSSEC in the DNSSEC section.
You will have to wait about 15 minutes for everything to propagate. At the conclusion of the 15 minutes, you will be able to go to every combination of your site, and it will redirect to https://www.example.com.
Some of the errors you may see along the way are as follows:
ACM Issue
On Heroku:
ACM is failing for 1 domain name
www.example.com Unable to resolve DNS for www.exampe.com
Solution: the reason you are seeing this is because your CNAME is not set up on Google Domains. Complete step (5) above to resolve this issue.
Extra Period Issue
(On Google Domains) "A period keeps getting added to the end of the "Data" section of the URL when I put it in."
Solution: This is expected.

My root domain isn’t working, what’s wrong?
Heroku Devcenter: Add a Custom Root Domain
I have followed all steps to set up my own Google domain that I purchased with Heroku. However when I have to enter the Synthetic Record Information I get an error that says:
This synthetic record has an error and will not function correctly:
The SSL Certificate for this domain hasn't been created yet. This process may take up to 24 hours to complete.
I am not sure what I did wrong. I selected to Temporarily redirect, do not forward path, and Enable SSL.
On the Heroku side the ACM status is labeled ask okay but when I click on the link to go to my webpage it does not work and I get an error from the browser that the server IP address cannot be found.
I have set up the CNAME and DNS target correctly as well.
You may need to add Custom resource records not Synthetic Record
And my other suggestion would be using Firebase if you purchased Google Domains.
They work well together. And Firebase provides free SSL too.
I have my DNS settings as shown in the image
DNS Setting along with an additional CNAME with host www and value as my GitHub page. Next I setup a CNAME entry in my GitHub page with an apex entry to my domain. The issue I face is that whenever I visit my domain with an https protocol, it shows a warning that the connection is not secure. I get the following in Chrome:
NET::ERR_CERT_COMMON_NAME_INVALID
How do I fix this? I have both https and http access for my domain.
UPDATE: Github introduced custom domain support for HTTPS on May 1, 2018.
If you are using GoDaddy and want to upgrade to HTTPS, do the following:
Go to DNS settings for your site in your GoDaddy account.
Remove all existing A records.
Open a terminal and do dig +noall +answer <YOUR-USERNAME>.github.io. You should see a table listing 4 slightly different IP addresses:
On GoDaddy, create 4 new A records, each one pointing to one of the IPs. For host use # and set the TTL to a low user-defined value (if you are in a hurry).
Go to your page repository settings on Github, and clear the custom domain name and save. Wait a while (minutes).
When executing dig +noall +answer <YOUR-CUSTOM-DOMAIN> yields the 4 IP addresses that you entered in the A records, go back to the Github repository settings and re-enter and save your custom domain name (which you just cleared) in the custom domain cell.
Optionally, check the box Enforce HTTPS. But make sure that https://<YOUR-DOMAIN>is responsive first.
Make sure you have a CNAME record in your DNS settings also. Host should be www and it should point to your <YOUR-USERNAME>.github.io.
Make sure there is a file in your website repository named CNAME containing the name of your custom domain (in my case ulfaslak.com).

GitHub pages does not support HTTPS for custom domains.
The only work around for doing so is to use an SSL provider as the middle man, such as Cloudflare. However, this would involve pointing your DNS name servers at Cloudflare's, which takes some time and complicates things.
If you want HTTPS support using GitHub pages you'll have to use GitHub's provided URL instead of your custom domain.
Another great option for static sites if you want custom domain name HTTPS is Amazon Web Services. You could set up an S3 bucket for your static website, configure CloudFront to distribute the static content, point your domain name at the CloudFront distribution, and use a free SSL certificate from Amazon's cert manager. This option comes out to less than $1/Month with a low-traffic website. A great in depth tutorial for that would be here.
I hope this answered your question! GitHub pages is a great hosting option, and it's not the end of the world if you decide to forget about HTTPS.
Custom domains on GitHub Pages gain support for HTTPS since May 01, 2018

I am having a domain chansek.com, hosted in Openshift through a Wordpress application. But the problem is, when I am trying to open my Wordpress Admin, it's always trying to connect through https instead of http. As I don't have any SSL certificate, it gives me some warning message. Please see the below screenshot for better understanding.
How do I make it go through http? I don't want any SSL certificate for my website as it's a personal blog.
I am also trying to use JetPack plugin. But it gives following error.
Your website needs to be publicly accessible to use Jetpack: site_inaccessible Error
Details: The Jetpack server was unable to communicate with your site
https://www.chansek.com [IXR -32300: transport error: http_request_failed SSL:
no alternative certificate subject name matches target host name 'www.chansek.com']
You have a couple of options:
1.) Disable using SSL for the admin in your wp-config.php file. (Openshift redirects wp-admin to https)
2.) Upgrade to the bronze plan and the purchase a custom ssl certificate and install it
You are getting that error from jetpack because the ssl certificate is not valid for your custom domain, only for your app-domain.rhcloud.com address.
