iOS 12 calendar iOS stock via caldav

Here’s how I attempt to set this up on my iPhone 7+ with iOS 13.1.2:

  1. Go to Passwords and Accounts
  2. Select Add Account
  3. Select Other
  4. Select Add CalDAV Account
  5. For Server, enter blackholeinc.net/remote.php/dav/principals/users/josef/
  6. For User Name, enter josef
  7. For Password, enter my password (with which I can log into the website from Chrome on Windows)
  8. For Description, enter BHICAL
  9. Select next
  10. Wait while the phone says “Verifying”
  11. Get this pop-up: “Cannot Connect Using SSL. Do you want to try setting up the account without SSL?”
  12. Select Cancel
  13. Get this pop-up: “Calendar Account. Unable to verify account information.”
  14. Select OK
  15. Select Advanced Settings
  16. Verify that Account URL says “https://blackholeinc.net/remote.php/dav/principals/users/josef/
  17. Verify that Use SSL is selected (green)
  18. Type 443 for the Port
  19. Go back to Caldav
  20. Select Next
  21. Get the same pop up as Step 11.
  22. Hit cancel
  23. Get the same popup as step 13.
  24. Recheck Advanced settings. They’re still the same as 16-18.
  25. Hit Save, on the off chance that it will work. :wink:
  26. It warns me it may not work.
  27. Go to the Calendar App
  28. Select Calendars
  29. Surprise - I see my calendar.
