All my instances appear to be running. When I connect to the respective domain, I get NSURLErrorCannotFindHost

Not sure what went wrong. It’s middle of the night and we get checkly notifications indicating that our websites are down.

Everything was running well. Now, my main website and other instances (*.mydomain.com) are not accessible.

What could have happened?

@Walter Pintor

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

Can you please provide more info on your architecture and DNS Configuration?

Are you using an Azure DNS Zone?

When you say "instances", are you using AKS?

Or individual Azure virtual machines and each virtual machine is mapped to one of your domain

VM 1 ----> abc.mydomain.com

VM 2 ----> def.mydomain.com

Or a different Azure PaaS Service altogether?

Please elaborate.

Cheers,

Kapil.
