Error : The resource you are looking for has been removed, had its name changed, or is temporarily unavailable

Add web.config file to your azure directory. Add the code below into it.

<configuration>
<system.webServer>
    <rewrite>
      <rules>
        <rule name="Main Rule" stopProcessing="true">
                <match url=".*" />
                <conditions logicalGrouping="MatchAll">
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                </conditions>
                <action type="Rewrite" url="/" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>
</configuration>

If you can't open a json file or any other file even though it exists, try to add:

<system.webServer>
<staticContent>
  <mimeMap fileExtension=".woff2" mimeType="application/x-font-woff" />
  <mimeMap fileExtension=".woff" mimeType="application/x-font-woff" />
  <mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>

It could help:

To remedy the problem, you need to provide a web.config file into your Angular 2 application.
