If an import from a Facebook iCalendar source isn’t working anymore, than it’s most likely the problem, that Facebook does not answer requests from my app with the iCalendar source, instead it sends a friendly “Browser is not supported”. This is the reason for this error message.

To resolve this issue, you can change the user agent in the settings in the section network settings. The user agent is the identity of the program which makes requests to a server. To get the import working again, just set the user agent for instance to curl.
