I will try to improve the script and be more informative.
List of working nodes - block streaming is a list of all nodes who could stream at least one block in 60s.
wss://appbasetest.timcliff.com was able to do this, https://appbasetest.timcliff.com was to slow.

List of working nodes - account history is a list of all nodes who could stream at list one account operation in 60 s.

The -1 in List of working nodes - api calls means that the node was needing to long or the output was empty.

I will increase the timeout from 60 seconds to 120 seconds.

Do you like the general idea to automatically generate a node report in this place?
