Shiny app downloadHandler timeout

The downloadHandler() function in Shiny apps times out after about 60 seconds. So if processing inside that function takes longer than 60 seconds, the download will fail.

Some potential solutions are discussed here.

Is there a ShinyProxy solution to this?


I think this is caused because you have a proxy or load-balancer in front of ShinyProxy. If that’s the case you will have to modify its configuration and increase the timeout for HTTP requests.
