Your provider started blocking Ookla so you stop noticing the speed dropping? ;)

no issues here

No idea what is going on, though the first suggestion wouldn't surprise me. Ookla worked normally for me until it stopped. It has been like this for at least a couple weeks, maybe longer. I can find nothing on the Internet about it. Every time I try to run it, I get a red rectangle with Page Error in it, and an additional message Error Fetching Resource. I get this on different computers. I have no idea what it means and can not find these errors on line. Every other speed tester I can find (about a half-dozen) works normally. So did Ookla until this problem occurred. I also tried speed tests on other sites, like Vodafone, that use Ookla but regardless of how I access it, I get the same error. And yes, this kind of thing seems to happen to me a lot.

what page (link) are you using?

what browser, try another one.

I just installed Firefox and received the identical error! Could this possibly have something to do with my ISP? I am on Netspeed RBI.

I have been trying different page links but I get the same result everywhere. Page loads then the error displays. Normally I use speedtest.net.

Try using a different ISP? Eg tether to your phone and test through that connection. 

Do you have a Windows 10 computer? If so try the Windows 10 Ookla Speedtest app.

You can also try speed tests at https://www.nperf.com/en/ and https://fast.com/ 

Do you have a VPN service, or an unblocking DNS service, or Ad blocking service running on you network?

Thanks for the responses. I get the same error on different computers running Win 7 and Win 10. I have not installed the app but I never needed it before. I do have DNS4ME but I just changed the settings back to the ISP default and I still get the same thing. I also have Windscribe VPN link on Chrome extension, but not installed and not active. The only common factor I can see to this if others are not getting the same thing, is the ISP or possibly the router, but I am not aware of any changes having been made at my end. Other speed tests all work normally. 

I cannot tether as I do not have (or want) a cell phone.

If you're not going to try the basic troubleshooting methods and you typically have multiple non-standard settings (non ISP DNS, VPN installed and I bet you have other extensions doing things like ad-blocking and cookie breaking), then I am pretty confident in saying it's something broken on your end - especially since no-one has reported the same thing on here yet.

Breaking the web Ookla app is 99% likely to be something with your browser or firewall/network setup.

Try the windows 10 app

Try Microsoft Edge and IE. (I suggest these because I doubt you use them normally and they are likely to be reasonably standard configs)

Once you get it working on your internet connection, then start disabling the additions to your setup one by one to figure out what's causing the issue.

(Of course I don't know what else you might have on your Network or PC that could be affecting your connectivity)

Instead of all that I tried something else. It is obvious and I should have thought of it before.

I have the Windscribe VPN with servers all over the world so I set it to New Zealand and then ran Ookla. It worked perfectly. I also tried a few other countries just for the fun of it. No problem. Then I turned the VPN off. Same problem.

I tried removing the DNS settings and using the ISP default (thus bypassing DNS4ME). I still got the error. I also tried a little Windows tablet I have, using Opera and no extensions or ad blockers or anything else in the way. I got the error. 

As stated previously, I have also tried Firefox, which I installed fresh with no add-ons. I got the error.

I have not tried the Win 10 app or Edge or IE. I don't want to mess with any Windows browsers and I only have Win 10 on one computer.

The fact that this works with a VPN, and only with a VPN, suggests to me that it must have something to do with my ISP, but I am no expert on this. I know there are some other people on Geekzone who use Netspeed and I would be very interested to know if any of them have the same issue when they try to run Ookla. 

Good luck getting your ISP to look into it further if you won't do some of the basic troubleshooting. The stuff you have done, while potentially valid, still leaves a bunch of stuff untested.

What basic troubleshooting are you going on about? What can Edge and IE do that Firefox doesn't? I can't tether and try a different provider because I don't have a phone. What else do you suggest?

Although the windows 10 app is indicated, They also offer a Mac app and Windows program (non store based)

I shifted rooms to where the Win 10 computer is and tried the app. It works fine but I still get the error when I try the link. This is not a big deal in itself. There are plenty of alternatives to Ookla. I would just like to know what the reason for this is in case  there may be other issues related to it.
