Genie.AppServer.ServersCollection(Task (failed) @0x00007fd08852fd00, nothing)

The link keeps loading and doesn’t work really,it shows Task failed too,so something is wrong

I have the exact same problem… I originally thought it was versioning but even downgrading doesn’t work… is it Julia or Genie because it’s the first thing on the Getting Started page…

Heya, as stated before I have run into the same problem… a temporary fix would be:
up(async = false) OR in my case I had to up(8001, async = false)

With Julia 1.5.2 and Genie 1.8.0 loading the page does work for me, but takes a few seconds the first time. Doing a down() and then up() again and then reloading the page is quick after that.

Edit: full trace

From the getting started code:

julia> using Genie, Genie.Router

julia> route("/hello") do
          "Hello World"
       end

julia> up()

The docs says immediately afterwards:

That’s all! We have set up an app, a route, and started the web server. Open your favourite web browser and go to http://127.0.0.1:8000/hello to see the result.

You have to go to: http://127.0.0.1:8000/hello
Not: http://127.0.0.1:8000 (which I also did by mistake).
