In the case I worked on, the project publishes successfully to Local IIS and Azure Functions but not to Azure App Service.

Solution

Follow the steps below to find a solution to this issue:

• Uninstall security software in the server and try again
• Make sure Management Services are installed (Add Role and Features > Web Server)
• Check if Web Management Services and Web Deploy Agent Service are running
• Make sure Fiddler or any other similar software is not running during the publish
• Check if TCP port 8172 are open
