It may be the storage endpoint suffix you're using in the initial deployment of the function app, if youre function app has its own storage account. In a test environment, we had core.windows.net hardcoded but then had an issue going to another environment, and the "404" for a function key update was referring to an internal error finding the container azure-webjobs-secrets.

We get the same error 'Not Found' when we try to set the masterKey via azure cli.

This does not work and returns Operation returned an invalid status 'Not Found'

az functionapp keys set -g 'RG' -n 'FNAPP' --key-type masterKey --key-name '_master' --key-value 'MYKEY'

Turns out, to set the masterKey you have to set it with the type functionKeys. So this does work:

az functionapp keys set -g 'RG' -n 'FNAPP' --key-type functionKeys --key-name '_master' --key-value 'MYKEY'

Seems wrong to me...
