Http Function fails to trigger randomly with COM exception

The HTTP function fails to trigger randomly, even with retries. What can be done at my end to make sure this doesn't happen?

Can you share your code?

Based on this: "System.Runtime.InteropServices.COMException : An operation was attempted on a nonexistent network connection. (0x800704CD)", it could be something related on the order of code executing things, like this: https://stackoverflow.com/questions/30706400/an-operation-was-attempted-on-a-nonexistent-network-connection-error-code-1229

Yes, I am still facing the issue, and it randomly pops up. I can provide the stack trace and invocation id. I have added retries, but it will keep failing once it starts to fail.

Microsoft.Azure.WebJobs.Host.FunctionInvocationException:

Hello,

I am facing the same issue whenever a third-party notification tries to reach out my function app.
The function app is hosted on a Consumption Plan. Is this the root cause?
I have never noticed this issue on the production environment where the func app is hosted on a Premium Plan.

Thank you and Best regrads,
Adriana
