Set-AzureRmAppServicePlan throws “Long running operation failed with status 'Conflict'” error

I was trying to go from a standard tier to the free tier and I got a conflict error.

There are many reasons that you might get this error and they are typically related to some functionality not available in the free tier that you enabled in paid tiers. To figure out why, go into your App Service Plan and look at your activity log. You should an entry for operation name: “Update hosting plan” with a status of failed. If you look at the “Json” and search for “statusMessage”, you should be able to figure out why.

In my case the error was caused by the fact that I was using a hybrid connection.

"Cannot change to the target SKU 'Free' because the Hybrid Connections count will exceed the new limit of '0'\"
