504.0 GatewayTimeout

[manuchadha1979]

Even after successful deployment, I am getting 504.0 GatewayTimeout when I click on the app url. I tried scaling up the app service but it still didn't work. Following are the logs from the app service

[manuchadha1979]

Seems the correct order to deploy is

az login
azd auth login 
azd up

I was able to deploy the application, however, I got error related to permissions. I have created a separate ticket for it
