hi,when I use the "display at UCSC main",I got an error:

"

• TCP non-blocking connect() to [link] timed-out in select() after 10000 milliseconds - Cancelling!
  Couldn't open http://[link]/root/display_as?id=9&display_app=ucsc&authz_method=display_at
  

"

how can I solve this problem?

look for your help,thanks!
