Hi Forest.
Just to let you know, we’re facing intermittent problems accessing app.forestadmin.com
since 2021-07-17 at about 07.00 UTC.
Since we’re using Heroku too, we told them the issue, wich is related to their DNS. And now they’re dealing with that.

Hope this information is useful to anybody experiencing the same problem.
