Hi Team,
I am experiencing the following error while trying to deploy a SharePoint Add-in,
Error occurred in deployment step 'Install SharePoint Add-in': The remote server returned an error: (403) Forbidden (Error Screenshot attached here).
However, the issue persists.
Could you assist me in diagnosing and fixing this issue?

Thank you for your question.
We are researching now and will get back to you once there is any update.
Your great patience is really appreciated.
Yes, please. Because of this 403 error we are unable to run the application.
Awaiting valuable response on the same.
Whether the account used to develop Add-in has admin role for the entire farm or for one site collection?
Please make sure the account has admin role for the entire farm.
Yes, it has admin rights, and it was working till last Thursday(19-Dec-24), but it got suddenly stopped next day. is there any deprecated SharePoint add in feature? If yes, then what would be the alternatives.
Have you installed update or made some changes for SharePoint server?
Per my knowledge, there is no deprecation for SharePoint Add-in feature.
