Speedtest by Ookla won't work on Mac
On my Macbook Pro with Apple M1 running Mac OS 14.1.2, I can't get Speedtest by Ookla to work. I have tried wired and wifi. I have tried Firefox & Safari. I have tried the native app. I have turned off App & Website Activity. I have turned off Content & Privacy. None of these settings has any effect.
I have tried on my work Mac (intel i5 running zSclaer) and my iPhone on the same network, and both work. I ran all the same experiments on my work Mac, and I can't get it to break.
I had Freedom.to installed on my personal Mac, but didn't try on my work Mac. I uninstalled on my personal Mac, just to try, but it didn't help the problem.
Does anyone have any suggestions? Thank you for your time!
MacBook Air 13″, macOS 14.1
