The link refers to an absolute path yes. /project/tes-2 is absolute, if it would be project/tes-2 then it would be relative.
But I think the issue lies within the CSS (styling) of your link itself.
It might be that the hyperlink itself doesn’t show up at the right place or that there is something on top of it preventing it from being clicked.
Maybe it’s an overkill for your purposes but you could remote debug your iOS-device.
Then you clearly see what’s going on. Is the ressource not accessible? Is the link-event not being triggered.
Nowdays debugging Safari mobile is even possible on win and linux machines.
