Azure Front Door SSL Certificate Update - azure

I have setup a Azure Front Door on top of my Function APIs. I have setup a custom domain and SSL certificate for the same. The certificate was bought from Azure and was set to auto renew. After a year , the certificate has got expired in the front door. The app service certificate was auto-renewed but the Front door did not get the update. I had to manually go to the site to update the certificate with the new secret from the key vault. Why is this happening? Shouldn't the certificate be updated automatically. Please advice.

Please refer to the below link, which says:
Certificate will auto renew within 90 days. But in case if it does not renews then even with less than 60/ 30 days, then need to file a ticket to the support team

Pending Issuance - Azure SSL App Service Certificate

I have a Azure Web App that has a SSL Certificate. This certificate is set to auto-renew.
However it has stopped working. When I log on to the Azure portal, it says "perform required domain verification" and the status of the Certificate says "Pending Issuance". The expiry date is yesterday, so I guess it has expired.
But....
Why didn't it auto-renew?
Why is it telling me to verify the domain again? (I did this when I bought it 2 years ago)
I looked at the steps in the portal to verify the domain by updating the txt record in my DNS.
Done that.
It's been like an hour and it still doesn't work.
Do I need to just wait?
Can anyone explain whats going on here?
Glad you got it working.Just to highlight on renewal of certificate.
As mentioned in this doc "Beginning September 23 2021, App Service certificates require domain verification during renew or rekey if you haven't verified domain in the last 395 days. The new certificate order remains in "pending issuance" during renew or rekey until you complete the domain verification.
Unlike App Service Managed Certificate, domain re-verification for App Service certificates is not automated, and failure to verify domain ownership will result in failed renewals. Refer to verify domain ownership for more information on how to verify your App Service certificate."
If you are going to renew/rekey your certificate, and it's been > 395 days since you last verified domain ownership, you would be required do verify domain ownership again in order to have the new certificate be issued to you. If it's been < 395 days, your certificate will be automatically issued again without additional action needed from you. Similar discussion here.
In the end what I did was delete the current Certficate and create a new one. - That got the site back up and running without waiting around.

Problem with SSL WIldcard Certificate on Azure App Service

Firstly I had working custom subdomain for my appservice.
Then I bought SSL wildcard Certificate and then generated pfx file with password. Next I uploaded certificate using Upload Certificate under Private Key Certificates. Certificate has Health Status = Healthy.
Finally, under binding tab I added TLS/SSL binging for my custom domain, choosen this certificate and its type = SNI SSL. Everything seems to be fine, undet custom domain there is SSL State = Secure and SSL Binding = SNI SSL.
When I go to my website - there is no information about any certificates.
I also tried the same with Create App Service Managed Certificate - the same effect, status Healthy, but certificate does not appear on the browser.
#mateuszwdowiak It sounds like you successfully added the SSL binding.
There are two main issues that I can think of that might have proceed the unexpected results that you encountered. Firstly, it can take some time for the SSL certificates to propagate out across the web. From my experience, I've seen it take up to 3 hours. Just because the Azure portal says it's binded, does not mean it will be getting served up just yet.
Secondly, I've seen browser cache also come into play.
It's been a few days but I wanted to see if you resolved this issue. If not, can you please try re-binding your wild card cert, wait up to 3 hours, and then using a fresh browsing session, attempt to browse your site. This should resolve the matter. If not, please reply back so we can assist you further.

Azure App Service - Does a new SSL Cert get automatically used?

We have an Azure app service which has an SSL cert which expires in about 30 days - I have purchased and installed a new SSL cert which is shown in the Azure portal as Healthy with the right expiry date - the about to expire SSL cert is also shown with a warning of its impending expiration.
My question is does the new SSL Cert automatically take over when the old one expires - or do I need to something else - e.g. delete the old SSL
Thanks in advance for any help with this
Firstly, Check whether you have enabled Auto Renew Option if not, find the below steps to enable auto renew .
if Auto Renew is on then it will be renewed automatically before it expires, the linked App Service Apps will be moved to the new certificate.
For Auto Renew App Service Certificate, you could check it in your App Service Certificate -> Auto Renew Settings -> Auto Renew App Service Certificate
below is the link to upload SSL certificate manually.
Or,
To upload your renewed certificate to your app service, also you can use this powershell command [New-AzureRmWebAppSSLBinding] (https://learn.microsoft.com/en-us/powershell/module/azurerm.websites/New-AzureRmWebAppSSLBinding?view=azurermps-6.6.0).
When the question 'Does my app service SSL cert get renewed automatically?' is asked the common response advises the questioner to check the 'Auto Renew' option. But when the SSL cert was purchased from a 3rd party and uploaded to the app service there is no 'Auto Renew' option available. This answer is to address that scenario.
The MS doc here gives details on what to do in an 'uploaded SSL' scenario.
Renew Certificate
Upload the new certificate to the app service via the TLS/SSL option
Bind the new certificate to the same custom domain without deleting the existing, expiring certificate.
Go to your App Service app's TLS/SSL settings pane, and select
'+Add Binding'. This action replaces the binding, rather than remove the existing certificate binding.
You can now delete the existing, expiring certificate
You need to follow these steps because the app service bindings will not automatically update for any hosts when the certificate has been manually loaded in to an App Service Private PFX Certificates.

Access denied for Service Fabric Explorer after certificate upgrade

I have been able to access Service Fabric Explorer with no problem, using a client certificate generated from Azure. The client certificate is still valid.
We recently added a new server certificate with a new thumbprint and set it to primary. (The previous server cert is secondary and hasn't been removed, if that matters.)
Now when I visit https://<name>.centralus.cloudapp.azure.com:19080/Explorer I get an error that varies by browser. There's no link to click through and ignore the warning.
In Edge: The website’s security certificate is not secure. Error Code: 0
In Chrome: You cannot visit <name>.centralus.cloudapp.azure.com right now because the website sent scrambled credentials that Google Chrome cannot process.
I can connect using the new certificate thumbprint via PowerShell.
You will need to add the certificate thumbprint under the cluster's client security.

How Do I Create a Production Client Authentication Certificate for Azure Key Vault?

I am learning about Azure Key Vault, and one of the scenarios it supports is certificate authentication, which you can read about here.
The samples do a great job of explaining how to make a self-signed certificate for local testing, which I have gotten to work without an issue. My question now is, how do I go about making a certificate for production deployments? Do I purchase this from a service somewhere? If so, what type of certificate do I need, exactly?
Unfortunately, there is no documentation anywhere that I could find in Azure Key Vault that outlines how to make (or what is expected/assumed) in a production-level certificate.
I basically have a few requirements/expectations based on my research/investigation so far:
I would like to use a trusted, external service (CA?) to purchase the certificate from.
The cheaper the certificate the better. :)
I would like to be able to create a certificate with custom data extensions.
In addition to my requirements, I have a specific question in regards to the certificate: What type of certificate do I need? Is this a server authentication certificate? Or a client authentication certificate? Or... ?
I have spent the past hour going through several SSL certificate providers, but none of them really could give me a great answer for the type of certificate I am looking for (when I provided the link to Azure certificate above to them). So, I decided to do what I should have done in the first place, and put my question up here to the esteemed community. :)
Thanks in advance for any assistance.
If you want the cert for SSL you want to get a Server Authentication certificate (it proves that the server, ie your site, is who it claims to be).
You can buy it from any trusted service and upload it to Azure Key Vault. Just google "buy ssl certificate". I think you can get one for as little as $30 if I remember correctly.
You can use Key Vault to enroll for certificate from public CAs such as DigiCert and GlobalSign. Look at the "Enroll programmatically from Public CA" section in https://blogs.technet.microsoft.com/kv/2016/09/26/get-started-with-azure-key-vault-certificates/
You can use the Key Vault REST API to programmatically enroll for certificates -https://learn.microsoft.com/en-us/rest/api/keyvault/createcertificate
The certificate policy allows for some customization like specifying which KeyUsage and EKUs you want in your certificate.
