ECONRRESET error slowing Vortex to a crawl!

[equisrider]

For the last few days, I'm getting errors following a VERY slow startup of the most recent Vortex mod manager.
I have opened my firewall (Comodo) wide for everything that connects to the Nexusmods.com domain, and specifically port 443 with no change. 

Same error. It makes playing impossible, and takes 40 seco0nds to respond to a click on a button.

Uninstalled and reinstalled the application with no change.
Running Windows 11 on a 1 Tb SSD internal with more than 66% free space.
The app is the only thing affected, and I'm not having issues logging into my account on any web browser.
Here is the detailed error report.  Please help.
