Incorrect custom certificate on mysite.scm.azurewebsites.net

Question

I've a strange problem: we have created a website and uploaded a custom SSL certificate. However, now the webdeploy publishing fails with some certificate error.

Upon looking closer I found that navigating to mysite.scm.azurewebsites.net yields a certificate error because the site is using the new custom SSL certificate instead of the default one issued to *.azurewebsites.net. What I can't understand is how it ended up using the custom certificate? All other websites we have, all of them using a custom SSL certificate, work fine and site.scm.azurewebsites.net always uses the default *.azurewebsites.net certificate.

Any ideas on how this happened and how I can have the scm.azurewebsites.net site use the default certificate?

Thanks!

Answer 1

Indeed, there is a known issue related to this. The good news is that there is an easy way to fix it:

• In the Azure portal, go to the Configuration tab for your site
• Go to the SSL bindings section. The assumption is that you have a binding set to 'IP based SSL'
• Change the binding to 'SNI SSL' and click Save
• Change it back to 'IP based SSL' and Save again

You should no longer have this issue.
