I have a Azure front door with no custom domains. I access front door on default domain assigned and it used to work, but since today morning I am getting invalid certificate error on accessing my APIs accessed through Front Door. On browsing Front door URL through browser following invalid certificate error screen is displayed:

In the screenshot you can see that front door domain is *.azurefd.net but certificate is from *.azureedge.net is this correct?
Can I do something to resolve this or this is an issue with Microsoft service?
