Curl problem running shiny application on local machine.

Good morning,

I have been working with this shiny application for over a year. I have never had a problem running the application locally or publishing to RStudio Connect. However, yesterday when attempting to run the app locally after some minor updates I have run into a bit of a problem. Again, this has never occurred before and I have yet to find a solution to this problem. Any help would be greatly appreciated!
