I have a Shiny app deployed the first time in 2017. I recently noticed the interactive map was not working properly so I updated the packages and deployed it again. I don't get any errors during deployment, and I can see it as "running" in Shinyapps.io, but I get a "504 Gateway Time-out" message when deploying and it just does not load (stays in "Please wait").
I couldn't find an answer anywhere. I've been trying for about 2 weeks. I made sure the files are not larger than 5MB and the overall size of the upload is below 20 MB.
Any help will be greatly appreciated!
