I have an azure function which suddenly stopped working.

If I open it in the portal I get an error message

Azure Functions Runtime is unreachable

The documentation says this is because the storage configuration is invalid. I have verified the storage account and it is correct and exact same configuration work in other functions.

When trying to investigate the cause, some things work while others just crash. e.g. open kudu shows a "yellow screen of death" with "the network path was not found".

Opening a console works but all commands give erros Azure console error

To solve it I just created a new function app with the same function and settings which works fine.

Now I'm just curious what the problem might be so I can detect/avoid it in the future.
