Hi McPherti
Firstly, it's great to see you back with us mate
I too have issues with being unable to access this site using Chrome and I think it is because Ausrock is not a secure site (https:) and Chrome doesn't like this
I use Edge but I had to tell it (in Settings) to allow this unsecure site - Chrome's equivalent setting doesn't work for some reason.
As far as getting erratic outcomes with your browser, I think it has to do with its Cache (bad data stops access, until the Cache is cleared) - maybe you restarted your PC in-between outcomes??)
Anyhow, let's hope you don't drop off the perch again - good luck.
