Attempting to download latest release for ReadyAPI and receiving Connection refused (loc: 4)

I went to check last week for any updates to ReadyAPI from the Help Menu, Check for updates .. but I keep getting this error (not using any VPNs or anything). This is the normal path I have upgraded the app in the past. Any suggestions?

I think I may be on the latest release (shown below) but want to ensure this works in the future for upgrades.
