deployment timeout error

Attempting to deploy a shiny app on (working perfectly fine locally). Here are the two issues I am facing:

  1. On initial app deployment success, I receive a 60.0 second timeout error with the reason that the server took too long. So i looked it up and tried using app_init_timeout(180) but i get the following error and the same 60.0 second timeout error on the app:

  1. I then attempted updating my app to see if the app gets started sooner on update, here's my app starting error log after the app gets successfully deployed. I am unable to find a solution to my HTTP 409 error.
