Problem to generate URL in walled garden hotspot

Hello!

I have some problems to try put web page on walled garden. In the Dst. host textbox have: *.youtube.com and in the Path textbox have /watch?v=KcdzdHoDvkg. The problem is when the URL is generated, in the walled garden entry show me this URL: *.youtube.com//watch?v=KcdzdHoDvkg and i can’t get access to watch this video.

I think the problem could be the double “//” in the URL generated. But i don’t know how to solve it. Any idea?

My router is a routerboard 951g 2HnD.

Thank you for your help.
