Hi @Emer163
Looks like you are trying to sync a Booking.com calendar to Airbnb? When reviewing Booking.com guidelines, it does say that not all properties are eligible to sync:
Booking.com Sync Calendars

If your property is eligible to sync, then a few suggestions:
- Try a different browser (if using chrome then try firefox)
- Try manually typing the URL by hand instead of copying and pasting it
Let us know here if you are able to get syncing successfully done....might help another Host experiencing the same problem. I don't use Booking.com, but have had similar issues with syncing Vrbo to Airbnb.
