Can't access any Drobo Apps via Dashboard

I have a Drobo 5N (original) that I’m trying to resurrect and use some apps. It seems like the apps that have been running for the past several years are still running and can be reached via the web addresses (Plex & Transmission).

However, when I try to start a new app and configure it, a white window appears that has the error “The Client sent a plain HTTP request, but this server only speaks HTTPS on this port.”

Does anyone know how to get around this? I can’t seem to configure Drobo Access or any apps at the moment.

Hello there!

Other than Plex and Transmission, what apps do you currently have installed? Does Drobo Dashboard ask you to update any apps when you start it?

Can you try to uninstall myDrobo and DroboAccess then reinstall them?
