BTW Diagnostic test won't work

[#1]

Ever since I have had Fibre I have been unable to run the BT Wholesale Diagnostic test.
The speed part of the test runs but the furether diagnostic part returns this error.

Your speed test has completed and the results are shown above, however during the test an error occurred while trying to retrieve additional details regarding your service. As a result we are unable to determine if the speed you received during the test is acceptable for your service. Please re-run the test if you require this additional information

I am using the FTTC part of the test.
Is there a solution to this issue?

Hi there,
Have you tried accessing the speed test directly here? http://speedtest.btwholesale.com/
In case you're experiencing speed issues we do request that customers try this but it's not essential if you can't get it to work.

I get the same, so will keep an eye on this thread in case there is an answer!
