CalDav setup for Yahoo Calendar doesn't work

Hello. I have created a new account by going to Menu>Accounts and choosing only the Yahoo calendar option under Calendar. I have used my Yahoo email address and have tried both App Password generated by Yahoo and my simple Yahoo email password. Neither work. Please help with a working configuration setup.

This is normally the default url below to access a Yahoo’s Calendar in eM Client apart from the username and password.

https://caldav.calendar.yahoo.com/.well-known/caldav

If you already have the above url and correct name and password, then could be a problem at the Yahoo end, then i would suggest to contact Yahoo via the following page to “verify your calendar login details”, and also “if there is any current calendar server outages” or changes in the Yahoo url etc.

Thank you very much @cyberzok. I appreciate your help. Yes, I was using the correct URL as you stated. My Yahoo login details are correct, and there are no server outages. I’m still testing/investigating …
