Hi,

I am getting this error for the ideogram track :

Error in .local(.Object, ...) : Failed to obtain 'hguid' cookie
Calls: IdeogramTrack ... browserSession -> new -> initialize -> initialize -> .local
Execution halted

Command : ideogram <- IdeogramTrack(genome = "mm10", chromosome = "chr6" , background.title = "black")


The commands runs fine locally, but gives an error on server. I suspect it might be internet connection problem.
Does Gviz needs some particular ports to be open to connect to UCSC?
Please help.

Thanks,
Sid
