I'm having the same issue: repeatedly getting the following message when I try to upload my updated app to shinyapps.io.
My error message...
Error: Unhandled Exception: Child Task 543634701 error: Unhandled Exception: HTTP 599: Timeout during request
Additionally, I get the following message when I try to restart the application from my dashboard...
Waiting for task: 543638153
deploying: Starting instances
Error: Unhandled Exception: Child Task 543638177 error: Unhandled Exception: HTTP 599: Timeout during request
I've seen solutions to keep trying, but wondering if there's another way.
