Fstab - Parse error at line

I'm giving up. I tried many changes, but can't find what is wrong. In fstab file I have this line:

https://webdav.pcloud.com /home/pi/pCloud davfs auto,_netdev,rw,user 0 0

If I try to "sudo mount -a", I'm getting an error:

mount: /etc/fstab: parse error at line 9 -- ignored

What is wrong? I tried with changing all parameters (step by step), but nothing helps. Folder is available, web address is available, options are correct, EOF is there ...

Any idea?
