Connecting to FastMail CalDav

Has anyone attempted to use the CalDav integration with FastMail? How did you get it to work? I created an app password and attempted to make a connection using their HTTPS connection and YCBM just said it couldn’t connect.

Thanks for any advice!

Not sure if anyone else can chime in here, but the few folks I tried to help with this we couldn’t get it to work. Our CalDav integration is very fickle and will only work when specific standards are met with the server we are trying to integrate with. You may want to double check with FastMail on the credentials as well.
