Are you still having this problem? Everything seems to be ok on our end.

Hello, I am not the original poster but we are having a similar/same issue

We are currently using IGV 2.12.3. When opening the Desktop app, we receive "Error loading genome: hg19". Pressing OK gives us " Unexpected error:null. See igv.log for more details". I do not know where to find igv.log

Clicking on Hg19 from the top left gives "The genome [Hg19] could not be read. Would you like to remove the selected entry?".

I have also tried Going to Genomes>Select Hosted Genomes and receive the error " Warning: could not connect to the genome server (https:\\s3.amazonaws.com/igv.org.genomes/genomes.tsv) Or locally defined genomes will be available." This opens to a "Hosted Genomes" window that is blank with nothing to select. I'm not sure if this is related.


Thank you,
Paul

Hi Paul,

The Amazon host that supported older versions of IGV (> 5 years old) is being decommissioned.   To fix this problem you need to edit your preferences.   Specifically select "View > Preferences > Advanced tab".   There is a field on this tab for the "Genome Server URL".   Replace the entry there with the following


You might run into other issues,  I will help you work around them, but this is the first step.
