Hi, Thanks for looking into this.
There is no specific error shown in Thunderbird, it just asks for the password again. My CalDAV app on android say Authentication Error.
The domain was already set up on the portal settings.
Here is the radicale logs with my domain and my email replaced with *s.
I picked a calendar from the web interface and got the CalDAV link and then added that to Thunderbird and the log in failed, I then checked the same password in an incognito window to log into the web interface again successfully.
These are all the entries in the radicale.log from doing that.
