error deploying shiny app with

I'm having a problem with the deployment of my app.
The code supposed to download some csv files from this pages: and', but when i try to read them trough the read.csv function it throws this message at the log console:

2020-06-06T01:03:57.306412+00:00 shinyapps[2416251]: Warning in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  :
2020-06-06T01:03:57.306414+00:00 shinyapps[2416251]:   entrada inválida encontrada en la conexión de entrada ''
2020-06-06T01:03:57.992442+00:00 shinyapps[2416251]: Warning in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  :
2020-06-06T01:03:57.992443+00:00 shinyapps[2416251]:   entrada inválida encontrada en la conexión de entrada ''

I know that the files have accents and already have tried to set the encoding to utf-8 or latin-1. ( fileenconding and encoding arguments from the function itself, also tried with the global encoding argument in options)

Any help will be appreciated.
Thanks in advance.

Here is my session info:

I can't reproduce your issue, I have made this minimal app to test deployment and there is no problem with the links you have provided the app deploys and runs as expected.


positvos_url <- ""
muertes_url <- ""

positivos <- read.csv(positvos_url)
muertes <- read.csv(muertes_url)

ui = fluidPage(

server <- function(input, output, session) {
  output$plot1 <- renderPlot({
    positivos %>% 
      mutate(FECHA_RESULTADO = dmy(FECHA_RESULTADO)) %>% 
      drop_na(FECHA_RESULTADO) %>% 
      count(FECHA_RESULTADO) %>% 
      ggplot(aes(x = FECHA_RESULTADO, y = n)) +
  output$plot2 <- renderPlot({
    muertes %>% 
      drop_na(FECHA_FALLECIMIENTO) %>% 
      count(FECHA_FALLECIMIENTO) %>% 
      ggplot(aes(x = FECHA_FALLECIMIENTO, y = n)) +

shinyApp(ui, server)

Can you provide a reproducible example (reprex) illustrating your issue? Please have a look at this resources, to see how to create one for a shiny app

andresrcs asked for a reprex which should be as close to a minimal example as you can make it with reasonable time and effort. You appeared to have shared a very large script, presumably much of which you don't need help with.

Its generally a good exercise to make a minimal app that explores your problem when you seek help with it, I often find when I take the time to make the example I solve the issue for myself and don't even need to go on to share it with the forum.

I strongly encourage you to start with an empty shiny app, and add in just the minimal code parts that approach what you wish to do, and still show the error/issue you face.
