Failure to automatically renew

[davidjade]

I've used the service for a long time but now none of my certificates are renewing as scheduled. I see no failures in the logs that I can find. Today, I had 0 days left on my certificates (got notified by Let's Encrypt email that they were expiring).

So I went into the function app web page and manually selected the certificates to renew and then it worked. It's just the automatic renew that doesn't work.

Steps to reproduce the behavior:

1. Just set it up to run automatically

• App Service OS: Windows
• App Service Type: Code? I just deployed by following the instructions here
• Runtime Stack: .NET
• Certificate Type: main domain and sub domains
