pi@raspberrypi:/opt/iobroker $ iobroker list instances
+ system.adapter.admin.0                  : admin                 : raspberrypi                              - disabled, port: 8081, bind: 0.0.0.0, run as: admin

wenn ich dann den admin state, ist der adapter admin kurz enabled, komme aber trotzdem nicht auf das Webinterface.

Ich kann auch keine zweite Instanz mit einem anderen Port anlegen:
