[galaxy-user] problem with displaying tracks from Galaxy

Hello all, we have the UCSC genome browser mirror as well as Galaxy mirror. The Galaxy has a feature enabling a user to display the data at UCSC genome browser as custom tracks. I have configured the galaxy to display the data to our UCSC browser mirror but it doesn't work properly: after the redirecting to genome browser page the "redirected to non-http(s): /root" error message is appeared. At the same time displaying Galaxy data at official UCSC works excellent. What are the possible reasons of it? Thank you in advance!
