I installed a fresh Gongorna image and the MOD-SDK is already installed.
However I'm having some problems with thumbnails generation.
During the wizard:
Create Icon Screenshot (same error "Can't generate thumbnail. Is your server running? Check the logs")
Deploy: ("Error: Can't install bundle. Is your server running? Check the logs.")
But, when I reboot the MOD-Host and the MOD-UI and add the pedal to the pedalboard the GUI loads correctly.
A little update!
The error in generation of thumbnails is only taking place in guitarix plugins. (Until now)
I have generated some GUIs for other plugins successfully! The error displayed in deploy continues, but the pedal GUI is updated correctly.
