Cannot access telehouse.net on mac but can on windows pc

Hi,
Bit of a strange problem.
On my iMac running latest version of os x with no additional security software, I am unable to access telehouse.net. I have tried Chrome, Safari & Firefox browsers.
I am, however, able to access telehouse.net on my Windows laptop, on the same internet connection.
If I use a VPN (F-Secure Freedome) on the iMac I CAN access telehouse.net no problem.

Any ideas ?

Presumably there must be something on the telehouse.net website that os x doesn't like and it blocks access. Freedome must be stripping out the information that os x doesn't like and os x then allows access.

Works fine for me- OS X 10.11.6 with both Safari and Chromium... have you tried a reboot? Personally, I don't find El Capitan as reliable as Apple's earlier OS's.

I have even tried installing a fresh copy of OS X with no other software installed.
Firewall on/off makes no difference.
The problem must be hardware related then if you can access it.
Strange 🤔

Just tried accessing the site on my iPhone from the same connection and that didn't work either. Then I tried using mobile data on the iPhone and I could access the site.
So for some strange reason the problem appears to be apple hardware combined with my BT connection doesn't work but other hardware (in this case a Windows 10 laptop) does work with the same connection.

Ignore this thread - I am continuing it in the technical discussion/technical issues sub-forum.
