I’m new to Nextcloud and recently signed up for an account with www.cloudfiles.at
I’m now trying to integrate my contacts with Thunderbird email client, so added Cardbook to Thunderbird. The problem I have is when trying to add a remote address book. I enter my url, then my email address and password and click validate. The validation always fails. I know the email address and password are correct as I used them to log in to my account via a browser and they work fine.
Am I missing something simple? Any help would be appreciated - I’m using Thunderbird 60.2.1 on Linux Mint 18.3
