Fiji Tutorial maker Login fails


I have an imageJ account to which I can log into normally. The account is also activated and the uploads to update sites work perfectly normal.

However, when I use the Tutorial Maker plugin (Plugins/Utilities/Fiji/New Fiji Tutorial) I get an error message by the console when I try to preview the tutorial.

Console says: “Failed to get session key!”.

Any idea what might be the reason?

Thanks for your help!
