Azure ASP,NET Core web app says "You do not have permission to view this directory or page"

Question

I just upgrading my Azure service from free level to basic level to get more file storage space. But now accessing my first newly deployed Web app shows: "You do not have permission to view this directory or page." The deployment from Bitbucket worked. The kudu console shows everything loaded. I have 3 branches in my repo and three Azure apps defined, one for each. Two were deployed before upgrading and they are okay. The third was just deployed after the upgrade and has this problem. All three come from the same repo, and at this time all three branches are basically the same. All are the same basic ASP.NET Core 1.0 web app for each branch. I checked a lot of google pages, but none were helpful. Where do I go to fix this?

Answer 1

This just means that the website didn't load so the IIS server is falling back and trying to load one of the html files it has in the list for startup which you wouldn't have since it should be loading up your site code instead, the directory listing is the last thing it could show and will fail in this scenario. Pay special attention to any differences in the deployment methods or any changes made to the Startup.cs file.
