Speedtest by Ookla keeps failing
Okay so I have been trying to run speed tests using the Ookla/Xfinity Speedtest.net for weeks and over a month now with no success. First I thought it was my router and actually there was a problem with my router so I bought a new one. I went from a single band Motorola Router to a Netgear Nighthawk router.
However I am still experiencing the same issue. The Comcast tech wanted to blame my iMac but the speed test doesn't fail when I use the Google speed test. Below is the image from the Ookla speed test.

Below is the results from the Google speed test for reference.
I talked with an Apple Representative weeks ago and they very kindly sat on the phone with me to help me run through a course of issues. Listing off all the settings in the original router. Even turning off my iMac's firewall, my Microsoft's Onedrive temporarily in case that might've caused it.
When I emailed Ookla support they claimed the website works on all of their Macs and they don't know what I'm doing wrong. That it must just be me and they don't know how to help me. The only other thing I can think of is that in the last round of Catalina security updates is when this issue started happening. I'll mention that obviously I'm connected to the internet when I am running these speed tests. This occurs whether I'm connected by way of ethernet or wifi.
If anyone can offer any advice or anything please throw a line.
