There is "Application error" in demo

[ghost]

I am aware of that

heroku server might be unstable because of too many requests being made to it

but http://osm-static-maps.herokuapp.com/ showing

 Application error

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail 

looks suspicious to me.

All demos reach a page error !

Now giving Forbidden, set correct header to access. Any chance of any maintainer looking into this?

Heroku is no more available because of pricing
