createTcpServer: address already in use error

Hello,

I created a Shiny app and have updated it and deployed it without issues in the past.

However, when I went to update it today, after I run rsconnect::deployApp() it says that it is successfully deployed but when I open up the app I get the error:

createTcpServer: address already in use error

How do I get it to successfully deploy and show the app?

Thanks!
