Horizon wont open

Welcome to the community. :slight_smile:

This is generally due to a security program on your PC or network blocking the connection.

Make sure Horizon is added as an exception in your antivirus.

Thanks for the info. Finally found it last night that my computer had updated and added a newer version of antivirus and it had it blocked.
