Hi @indraraj26, my two cents would be that the index.html is cached which in such case is more of a server configuration rather than an Angular CLI issue.

Unfortunately, there isn’t much information in this issue to validate if this is the real issue or not.

[indraraj26]

I will share website link tmrw it is hosted on aws s3 bucket. btw from where i can start to troubleshoot. how can i blame server team, it is an server side issue.

[alan-agius4]

Let's not play the blame game 😁.

You can try to checking what the response for the index.html is and verify if that's the cached version or not.

For additional information on server cache settings, this article may be useful: https://web.dev/http-cache/

The Cache-Control header should typically be set to no-cache for the index.html. This can be checked in the dev tool's network tab of the browser.

Thank Alan and clydin for quick response on this. I will check this in morning and will update accordingly.

Hello,
Since Angular 7 i get this error: Unknown option: '--output-hashing'

What would be the right way to use this option ?

Thank you

Thank you

—-output-hashing is a build option. See: https://angular.io/cli/build

@indraraj26, shall we close this?

[indraraj26]

Thank you for patience and i am really sorry for late response on this. yes i am closing since server team is looking into that.
