Foxfang

When I start the download of any forge everything seems to work but once I try to open the installer and download the client it stops working I've looked in the log while doing so and the first thing that pops up once the download starts is, forge-1.12.2-14.23.5.2768-universal.jar ing {Wrong Side} this happens to all the different versions not just 1.12.2

For some reason when I try to download forge 1.12.2 onto my Mac it starts downloading then stops. In the log it says, not downloading {wrong side}, next to all the considering librairies. Anyone know how to fix this?
