Configure the update with different soucrce

Hi,
I used to use the openelec dev update to update to milhouse builds.
Now with Libreelec there is a funtion to do this in the setup.
But I have tried with no result.
I am using this link:
Index of /builds/master/
Also tried:
Index of /builds/master/Generic/
With no result allways says link not valid?
Any Help?
Thanks,
Jose

Thanks it worked I was missing a slash
Stupid me.
Thanks
