Azure FunctionApp trigger functions(Http/timer) are not loading

Bharath 10

I have a functionApp deployed in a virtual network in an azure subscription. The functionApp is set up with a private storage acccount thorugh a private endpoint. when I deploy the functionApp through the cli it deploys successfully. On deploying when I goto AzurePortal I am facing this problem consistently when i try to Test/Run the function. function_not_loading - Copy

I have set all the required settings in functionApp settings. The problem is once the build is over and when click on Test/Run for the timer-fn it worked the first time, but after the error is very consistent. Even after deleting the function app and redeploying it (without any errors) the function app trigger functions are not loading even though in the overview page i can see both(http/timer).

When I check the activity log i get this error

syncWebApp-functionsTriggers

Any help is appreciated

@Bharath Thanks for reaching out. Can you please review the Diagnose and solve problems blade on your function app to get more details on the Service Unavailable error. Is your storage account used for your function app is accessible by function app.

In Diagnose and Solve Problems, under the getting this error under functionapp settings.

This error has already taken care of and

AzureFunctionsWebHost__hostid

is set with just 31 characters. so not sure why this is getting thrown

Also in the network connectivity pane this is showing up

@Bharath Apology for missing your last response. For your network issue have you configured the vnet configuration correctly as per the error looks like the function app storage account is not able to communication with your function app. You can validate vnetrouteallenabled is set to 1 or not if outbound traffic from the app is routed through the virtual network.
